Description
NCP5663DSADJR4G is ON Semiconductor’s NCP5663 family DC-DC buck regulator, in the adjustable-output DSADJ variant with DJR4G packaging (RoHS, tape-and-reel). It’s intended for portable/battery-powered electronics requiring efficient conversion of a higher input to a stable lower voltage. The device integrates the switching regulator core (high-side switch) and requires only external passive components: an inductor, input/output capacitors, and a feedback network to set Vout. Typical features include adjustable output, wide input range, protection functions (overcurrent/short-circuit, thermal/UVLO), and good light-load efficiency. Applications include wearables, smartphones, IoT sensors, and automotive subsystems needing compact, efficient power management. For exact electrical specs (VIN range, VOUT, switching frequency, current limit, package details), consult the official ON Semiconductor datasheet and product brief.
Pinout
Pin count: 8 pins.
Function: NCP5663DSADJR4G is an adjustable buck (step-down) DC-DC switching regulator with an integrated switch. It regulates higher input voltages down to a desired output via an feedback (FB) pin, with enable/soft-start and other control pins (e.g., VIN, SW, GND, EN).
