MCP1630V-E

Microchip Tech · AC-DC Controllers And Regulators · MSOP-8

MCP1630V-E from Microchip Tech, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COMP output Error amplifier output, with external compensation connected from FB to COMP; an internal clamp limits the COMP voltage to 2.7 V (typ.), which sets the maximum peak current limit.
2 FB input Error amplifier inverting input that receives the regulated output (voltage or current) for negative feedback regulation.
3 CS input Current sense input for cycle-by-cycle peak current control (0.9 V max on MCP1630) or voltage ramp input on MCP1630V (2.7 V max), where CS must be less than or equal to VIN - 1.4 V for normal PWM operation.
4 OSC IN input External oscillator input, typically driven by an MCU I/O pin; a high level forces VEXT low, and its duty cycle sets the maximum converter duty cycle.
5 GND power_in Circuit ground, which should be connected to a quiet analog ground plane because noise here affects the CS versus error amplifier output comparison.
6 VEXT output External driver output that sets the power system duty cycle; it drives a logic-level MOSFET driver input for high-power or high-side use, or directly drives an N-channel MOSFET gate in low-power low-side applications.
7 VIN power_in Input bias supply that must be between +3.0 V and +5.5 V, with a 0.1 µF bypass capacitor connected between VIN and GND.
8 VREF power_in External reference input that sets the regulated output, with a range of 0 V to VIN (rail-to-rail).
