NCP2991 1.35 Watt Audio Power Amplifier with Selectable Fast Turn On Time
The NCP2991 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP2991 is capable of delivering 1.35 W of continuous average power to an 8.0 W BTL load from a 5.0 V power supply, and 1.1 W to a 4.0 W BTL load from a 3.6 V power supply. The NCP2991 provides high quality audio while requiring few external components and minimal power consumption. It features a low-power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The NCP2991 contains circuitry to prevent from "pop and click" noise that would otherwise occur during turn-on and turn-off transitions. It is a zero pop noise device when a single ended or a differential audio input is used. For maximum flexibility, the NCP2991 provides an externally controlled gain (with resistors). In addition, it integrates 2 different Turn On times (15 ms or 30 ms) adjustable with the TON pin. Due to its superior PSRR, it can be directly connected to the battery, saving the use of an LDO. This device is available in a 9-Pin Flip-Chip CSP (Lead-Free).

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at TA = +25C. 2. The thermal shutdown set to 160C (typical) avoids irreversible damage on the device due to power dissipation. 3. The RqJA is highly dependent of the PCB Heatsink area. For example, RqJA can equal 195C/W with 50 mm2 total area and also 135C/W with 500 mm2. The bumps have the same thermal resistance and all need to be connected to optimize the power dissipation. 4.

APPLICATION INFORMATION
Detailed Description
The NCP2991 audio amplifier can operate under 2.5 V until 5.5 V power supply. With less than 1% THD + N, it can deliver up to 1.35 W RMS output power to an 8.0 W load (VP = 5.0 V). If application allows to reach 10% THD + N, then 1.65 W can be provided using a 5.0 V power supply. The structure of the NCP2991 is basically composed of two identical internal power amplifiers; the first one is externally configurable with gain-setting resistors Rin and Rf (the closed-loop gain is fixed by the ratios of these resistors) and the second is internally fixed in an inverting unity-gain configuration by two resistors of 20 kW. So the load is driven differentially through OUTA and OUTB
outputs. This configuration eliminates the need for an output coupling capacitor.
Internal Power Amplifier
The output PMOS and NMOS transistors of the amplifier were designed to deliver the output power of the specifications without clipping. The channel resistance (Ron) of the NMOS and PMOS transistors does not exceed 0.6 W when they drive current. The structure of the internal power amplifier is composed of three symmetrical gain stages, first and medium gain stages are transconductance gain stages to obtain maximum bandwidth and DC gain.

NCP2991
Turn-On and Turn-Off Transitions
When a shutdown low level is applied, the output level is tied to Ground on each output after 10 ms. With TON = GND, turn on time is set to 30 ms. With TON = VP, turn on time is set to 15 ms. To avoid any pop and click noises, Rin * Cin < 2.4 ms with TON = GND and Rin * Cin < 1.2 ms with TON = Vp. The electrical characteristics are identical with the 2 configurations. This fast turn on time added to a very low shutdown current saves battery life and brings flexibility when designing the audio section of the final application. NCP2991 is a zero pop noise device when using a single-ended or differential audio input configuration.
Shutdown Function
- The possible output power is four times larger (the output swing is doubled) as compared to a single-ended amplifier under the same conditions. - Output pins (OUTA and OUTB) are biased at the same potential VP/2, this eliminates the need for an output coupling capacitor required with a single-ended amplifier configuration. The differential closed loop-gain of the amplifier is given by Avd + 2 * f + orms . Rin Vinrms Output power delivered to the load is given by
Porms + (Vopeak)2 (Vopeak is the peak differential output 2 * RL R V
The device enters shutdown mode when shutdown signal is low. During the shutdown mode, the DC quiescent current of the circuit does not exceed 100 nA. In this configuration, the output impedance is 8.5 kW on each output.
Current Limit Circuit
voltage). When choosing gain configuration to obtain the desired output power, check that the amplifier is not current limited or clipped. The maximum current which can be delivered to the load is 500 mA Iopeak +
Vopeak . RL
The maximum output power of the circuit (Porms = 1.0 W, VP = 5.0 V, RL = 8.0 W) requires a peak current in the load of 500 mA. In order to limit the excessive power dissipation in the load when a short-circuit occurs, the current limit in the load is fixed to 1.1 A. The current in the four output MOS transistors are real-time controlled, and when one current exceeds 1.1 A, the gate voltage of the MOS transistor is clipped and no more current can be delivered.
Thermal Overload Protection
Gain-Setting Resistor Selection (Rin and Rf)
Internal amplifiers are switched off when the temperature exceeds 160C, and will be switched on again only when the temperature decreases fewer than 140C. The NCP2991 is unity-gain stable and requires no external components besides gain-setting resistors, an input coupling capacitor and a proper bypassing capacitor in the typical application. The first amplifier is externally configurable (Rf and Rin), while the second is fixed in an inverting unity gain configuration. The differential-ended amplifier presents two major advantages:
Rin and Rf set the closed-loop gain of the amplifier. In order to optimize device and system performance, the NCP2991 should be used in low gain configurations. The low gain configuration minimizes THD + noise values and maximizes the signal to noise ratio, and the amplifier can still be used without running into the bandwidth limitations. A closed loop gain in the range from 2 to 5 is recommended to optimize overall system performance. An input resistor (Rin) value of 24 kW is realistic in most of applications, and doesn't require the use of a too large capacitor Cin.
Input Capacitor Selection (Cin)
The input coupling capacitor blocks the DC voltage at the amplifier input terminal. This capacitor creates a high-pass filter with Rin, the cut-off frequency is given by
fc +
The size of the capacitor must be large enough to couple in low frequencies without severe attenuation.
