LA8522A Datasheet | INNO-TECH

300KHz, 2A/23V Step-Down DC-DC Converter General Description LA8522A is a voltage mode, step-down DC-DC converter that is designed to meet 2A output current, and utilizes PWM control scheme that switches with 300KHz fixed frequency. The input voltage range of LA8522A is from 3.6V to 23V, and available in adjustable output voltage from 0.8V to VIN. The supply current is only 3m A during operation and under 1u A 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 current limit, thermal shutdown protection, and short circuit protection are also included. Due to the low RDS(ON) of the internal power MOSFET, this device provides high efficiency step-down applications. It can also operate with a maximum duty cycle of 100% for use in low drop-out conditions. The package is available in standard SOP-8.
