GENERAL DESCRIPTION

The AAT1107 provides an integrated two-channel

pulse-width-modulation (PWM) solution for the

power supply of DC-DC system.

offers system engineers the flexibility to tailor-make

the power supply circuitry for the specific

applications.

Each channel contains its own error amplifier,

PWM comparator, dead-time control (DTC) and

output driver. The two channels share common

features of under-voltage protection, oscillator,

short circuit protection and voltage reference circuit.

Two dead-time control inputs are assigned for

channel (CH1) and channel 2 (CH2) individually,

and dead-time control inputs can be used to control

on/off operation.

The AAT1107 contains one step-up (boost) circuit

at CH2 and one inverting (buck_boost) circuit at

CH1. In addition, DTC can be set to provide 0%

to 100% dead-time through a resistive divider

network and soft-start can be implemented by

paralleling the DTC resistor with a capacitor.

The Maximum output current of LDO regulator can

be enlarged by connecting an nMOSFET (or NPN

bipolar) as a source follower stage at OUT3 pin.
