SW605 zero-current resonant switch power supply controller is a single-chip integrated circuit manufactured by silicon bipolar power IC technology. The circuit contains 5V± 5% reference source, VCO, divider, single-stable, power supply undervoltage, overload and overload delay recovery, soft start, power output and other functions.
This document describes the SV605 zero‑current resonant switch‑mode power supply controller, its integrated functions such as reference source, phase splitter, soft‑start, overload protection, and remote shutdown. It outlines the recommended operating conditions and the pin‑out assignments for the 16‑lead DIP package.
Technical specifications, electrical characteristics, and calculation formulas for remote shutdown current, overload delay, soft‑start time, and pulse width are included, along with practical usage notes for high‑frequency, high‑current designs. This manual is written in Chinese.
| Input supply voltage | 10 V ~ 20 V |
|---|---|
| Operating temperature range | -55 °C ~ 125 °C |
| Output pulse rise time | < 40 ns |
| Output pulse fall time | < 30 ns |
| VCO linear error | < +5 % |
| Maximum supply voltage (absolute rating) | 22 V |
The controller is designed to operate with an input voltage between 10 V and 20 V.
It can function from –55 °C up to 125 °C.
The remote shutdown current is calculated using the formula provided in the manual under the remote shutdown section.
