SP5620HP (DIP IC)

The SP5620HP is a switch-mode DC-DC step-down (buck) regulator IC commonly used in power supply modules and general electronics projects.

Key Features

• Type: Buck (step-down) switching regulator

• Package: DIP (through-hole, easy to solder)

• High efficiency compared to linear regulators

• Wide input voltage range (depends on design)

• Built-in switching transistor

• Supports external inductor, diode, and capacitors

Typical Applications

• DC power supply modules

• Arduino / MCU power regulation

• Industrial control boards

• Battery-powered devices

• DIY electronics projects

General Function

It converts a higher DC input voltage into a lower, stable DC output voltage with better efficiency than 78xx linear regulators—especially useful when input voltage is much higher than output voltage.

Notes

• Output voltage is usually set using external resistors

• Requires proper inductor and Schottky diode selection

• Heat dissipation is lower than linear regulators, but layout still matters
