LTC3896EFE#PBF

DC DC Switching Controllers Overview

The LTC3896EFE#PBF is a high-performance inverting DC/DC switching regulator controller manufactured by Analog Devices Inc. It converts a wide-ranging positive input voltage source into a regulated negative output that can reach up to 60V below ground. The device drives an all N-channel synchronous power MOSFET stage, supporting an input voltage range of 4V to 150V and delivering an output current of 2A. It operates with a fixed switching frequency of 900kHz and features a low quiescent current of 40µA. The component is housed in a TSSOP-EP-38 package and supports an operating temperature range from -40°C to +150°C.
