General Description
LA8506
500KHz, 3A/40V Step-Down DC-DC Converter
Features
LA8506 is a current mode, step-down DC-DC converter that is designed to meet 3A output current, and utilizes PWM control scheme that switches with 500KHz fixed frequency.
The input voltage range of LA8506 is from 8V to 40V, and available in adjustable output voltage from 1.222V to 24V. The supply current is only 1mA during operation and under 30uA 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 soft-start current limit, thermal shutdown protection, and short circuit protection are also included.
