GENERAL DESCRIPTION
The AAT1401 provides an integrated four 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 (DTC) and output driver. The under-voltage
protection, oscillator, short circuit protection and voltage
reference circuit are the common features for the four
channels.
In addition to a boost conversion, AAT1401 also has two
synchronous rectification systems with alternatives of a
synchronous boost or buck on channel one (CH1) and a
boost or buck conversion on channel two (CH2).
