LA8525

LA8525A : General Description LA8525/A 500KHz, 2A/21V Step-Down DC-DC Converter Features LA8525/A is a current mode, step-down DC-DC converter that is designed to meet 2A output current, and utilizes PWM control scheme that switches with 500KHz fixed frequency. The input voltage range of LA8525/A is from 4.5V to 21V, and available in adjustable output voltage from 0.8V to VIN. The supply current is only 1mA during operation and under 20uA 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 pr.
