Download the LA8521 datasheet PDF. This datasheet also covers the LA8521-INNO variant, as both devices belong to the same 5a/23v step-down dc-dc converter family and are provided as variant models within a single manufacturer datasheet.

Description

LA8521 300KHz, 5A/23V Step-Down DC-DC Converter

Features

  • LA8521 is a voltage mode, step-down DC-DC converter that is designed to meet 5A output current, and utilizes PWM control scheme that switches with 300KHz fixed frequency. The input voltage range of LA8521 is from 3.6V to 23V, and available in adjustable output voltage from 0.8V to VIN. The supply current is only 3mA 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 lin.
