LTC3863IDE#TRPBF

DC DC Switching Controllers Overview

The LTC3863IDE#TRPBF is an inverting DC/DC controller manufactured by Analog Devices Inc., designed to convert a positive input voltage into a negative output using a single inductor. It operates within an input voltage range of 3.5 V to 60 V and delivers a negative output voltage between -150 V and -400 mV. The device supports a maximum output current of 20 mA with two available outputs. Switching frequency is adjustable from 50 kHz to 850 kHz, while the quiescent supply current is specified at 50 uA. Load regulation is rated at -0.015%. The component functions reliably across an operating temperature range of -40°C to +150°C and is housed in a DFN-12 surface-mount package.
