MAX761CSA

Voltage Regulators - DC DC Switching Regulators Overview

The MAX761CSA is a boost switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 2V to 16.5V and provides a fixed 12V output or adjustable output up to 16.5V via external resistors. The device delivers a maximum switch current of 150mA at a switching frequency of 300kHz. It features an internal 1A N-channel power MOSFET and utilizes current-limit pulse frequency modulation control. The component is housed in an 8-SOIC surface-mount package and supports operation temperatures from 0°C to 70°C.
