LTC7138 Overview
Key Specifications
Package: MSOP
Mount Type: Surface Mount
Pins: 16
Max Voltage (typical range): 140 V
Description
The LTC®7138 is a high efficiency step-down DC/DC regulator with internal power switch that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. The LTC7138 can supply up to 400mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency and for reducing output ripple and component size.
