GENERAL DESCRIPTION
The AAT1403A provides an integrated six-channel
pulse-width-modulation (PWM) solution for the power
supply of DC-DC converter; this device offers system
engineer flexibility to tailor-make the power supply
circuitry for specific applications. Each channel
contains its own error amplifier, PWM comparator,
dead-time control and output driver. The under-voltage
protection, oscillator, short circuit protection and
voltage reference circuit are the common features for
the six channels.
In addition to two boost conversions and one inverting
conversion, AAT1403A also has three synchronous
rectifiers.
