LA8509 380KHz, 18V/3A Synchronous Step-Down DC-DC Converter General Description Features The LA8509 is a current mode, synchronous step-down DC-DC converter that is designed to meet 3A output current, and utilizes PWM control scheme that switches with 380KHz fixed frequency. The input voltage range of LA8509 is from 4.5V to 18V, and available in adjustable output voltage from 0.925V to 12V. The supply current is only 1.2mA 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 due to the current mode operation. Other features of current limit, soft-start, thermal shutdown protection, and short circuit protection are also included.
