The AAT1107 provides an integrated two-channel
pulse-width-modulation (PWM) solution for the
power supply of DC-DC system. This device
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.
