1MHz, 5V/2A Synchronous Step-Down Converter
General Description
The LA8040 is a current mode, synchronous
step-down DC-DC converter that is designed to
meet 2A output current, and utilizes PWM
control scheme that switches with 1MHz fixed
The input voltage range of LA8040 is from 2.5V
to 6V, and available in adjustable output
voltage from 0.8V to VIN. The supply current is
only 0.6mA during operation and under 25uA in
This device provides an enable function that can
be controlled by external logic signal. It also
provides excellent regulation during line or load
transient due to the current mode operation.
Other features of soft-start, current limit,
thermal shutdown protection, short circuit
protection, and over voltage protection are also
included. The under voltage lockout prevents
low input voltage start-up until it reaches the
UVLO threshold voltage. It is available in the
Exposed Pad SOP-8 (ESOP) package.
