LA8040
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 frequency.
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 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 due to the current mode operation.
