High Light-Load Efficiency, Dual-Output,
Main Power Supply Controllers
ISL8112 is a dual-output Synchronous Buck controller with 2A
integrated driver. It features high light load efficiency which is
especially preferred in systems concerned with high efficiency
in wide load range, like the battery powered system. ISL8112
includes two constant on-time PWM controllers. Either of the
two outputs can operate in output fixed mode or adjustable
mode. In fixed mode, one output can be 5V or 3.3V and the
other can output 1.5V or 1.05V. In output adjustable mode,
one output can be 0.7V to 5.5V, and the other output can
range from 0V to 2.5V (sensing output voltage directly) or up
to 5V (using resistor divider voltage for voltage sensing). This
device also features a linear regulator providing 3.3V/5V, or
adjustable from 0.7V to 4.5V via LDOREF. The linear
regulator provides up to 100mA output current with automatic
linear-regulator bootstrapping to the BYP input. When in
switch over, the LDO output can source up to 200mA.
ISL8112 includes on-board power-up sequencing, the power-
good (PGOOD_) outputs, digital soft-start, and internal soft-
stop output discharge that prevents negative voltages on
shutdown.
ISL8112 is implemented with constant on-time PWM control
scheme which need no sense resistors and provides 100ns
response to load transients while maintaining a relatively
constant switching frequency. The unique ultrasonic pulse-
skipping mode maintains the switching frequency above
25kHz, eliminating undesired audible noises in low frequency
operation at light load. Other features include pulse skipping
which maximizes efficiency in light-load applications, and
fixed-frequency PWM mode which reduces RF interference in
sensitive applications.
