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 comparator, 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 comes with a fixed 380kHz
oscillator, however, when the feedback voltage is lower
than 0.7V, the switching frequency changes to 47kHz
and returns to 380kHz after the short-circuit is
released.
