GENERAL DESCRIPTION
The AAT1346A/B/C is a 2A 15V step-down converter, which provides an integrated one-channel PWM solution for the power supply of DC-DC system. It offers system engineers the flexibility to tailor-make the power supply circuitry for specific applications. The buck PWM contains enable control signal, error amplifier, PWM parator, output driver, under-voltage protection, oscillator, short circuit protection and voltage reference circuit. The AAT1346A/B/C contains one buck current mode PWM with internal PMOS. In addition, a digital soft-start is also included to prevent inrush current at startup. AAT1346A/B/C es with a fixed 380k Hz oscillator, however, when the feedback...
