GENERAL DESCRIPTION
The AAT1403B 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, AAT1403B also has three synchronous rectifiers.
