It operates from a 3.5V to 16V supply rail and drives an external transistor switch, making it suitable for battery-powered or industrial power supplies that need a regulated output from a varying input source. ## Parametric fit for the BOM The controller delivers a single positive output using a single external N-channel MOSFET or IGBT—the Transistor Driver output type means the controller itself handles the gate drive, not the power path. The 3.5V minimum supply means it can start from a 3.7V Li-ion cell near end-of-discharge, while the 16V maximum covers 12V rails with margin. Control features include an Enable pin for shutdown, Frequency Control to set the switching frequency with an external resistor, and a Ramp pin for slope compensation—these give the designer direct control over the converter's stability and noise profile without needing an external PWM generator. The -40°C to 125°C junction temperature range qualifies it for industrial and automotive environments where the ambient temperature inside an enclosure can exceed 85°C. The 20-SSOP package (5.30mm body width) is a surface-mount footprint that suits compact PCB layouts without requiring a thermal pad for power dissipation—the controller's own dissipation is low because the power switch is external.","metaTitle":"MCP1631HV-500E/SS Sepic Controller, Step-Up/Down, 20-SSOP","metaDescription":"Microchip Technology MCP1631HV-500E/SS Sepic controller, 3.5V-16V supply, -40°C to 125°C, 20-SSOP.
