LA8522
300KHz, 2A/23V Step-Down DC-DC Converter
General Description
Features
LA8522 is a voltage mode, step-down DC-DC
converter that is designed to meet 2A output
current, and utilizes PWM control scheme that
switches with 300KHz fixed frequency.
The input voltage range of LA8522 is from 3.6V
to 23V, and available in adjustable output
voltage from 0.8V to VIN. The supply current is
only 3mA during operation and under 1uA in
shutdown.
This device provides an enable function that
can be controlled by external logic signal. It
also provides excellent regulation during line
or load transient. Other features of current
limit, thermal shutdown protection, and short
circuit protection are also included. Due to the
low RDS(ON) of the internal power MOSFET, this
device provides high efficiency step-down
applications. It can also operate with a
maximum duty cycle of 100% for use in low
drop-out conditions. The package is available
in standard SOP-8.
