NCP9002
1.3 Watt Audio Power
Amplifier with Fast Turn On
Time
The NCP9002 is an audio power amplifier designed for portable
communication device applications such as mobile phone
applications. The NCP9002 is capable of delivering 1.3 W of
continuous average power to an 8.0 W BTL load from a 5.0 V power
supply, and 1.0 W to a 4.0 W BTL load from a 3.6 V power supply.
The NCP9002 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 NCP9002 contains circuitry to prevent from “pop and click”
noise that would otherwise occur during turn−on and turn−off
transitions.
For maximum flexibility, the NCP9002 provides an externally
controlled gain (with resistors), as well as an externally controlled
turn−on time (with the bypass capacitor). When using a 1 mF bypass
capacitor, it offers 100 ms wake up time.
Due to its excellent 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 = +25°C.
2. The thermal shutdown set to 160°C (typical) avoids irreversible damage on the device due to power dissipation. For further information see
page 9.
3. The RqJA is highly dependent of the PCB Heatsink area. For example, RqJA can equal 195°C/W with 50 mm2 total area and also 135°C/W with
500 mm2. For further information see page 10. The bumps have the same thermal resistance and all need to be connected to optimize the power
dissipation.
4. Human Body Model, 100 pF discharge through a 1.5 kW resistor following specification JESD22/A114.
5. Machine Model, 200 pF discharged through all pins following specification JESD22/A115.
6. Maximum ratings per JEDEC standard JESD78.
