Product Highlights
Lowest System Cost with Enhanced Flexibility
• Simple ON/OFF control, no loop compensation needed
• Selectable current limit through BP/M capacitor value - Higher current limit extends peak power or, in open frame applications, maximum continuous power - Lower current limit improves efficiency in enclosed adapters/chargers - Allows optimum TinySwitch-III choice by swapping devices with no other circuit redesign
• Tight I2 f parameter tolerance reduces system cost - Maximizes MOSFET and magnetics power delivery - Minimizes max overload power, reducing cost of transformer, primary clamp & secondary components
• ON-time extension – extends low line regulation range/
hold-up time to reduce input bulk capacitance
• Self-biased: no bias winding or bias components
• Frequency jittering reduces EMI filter costs
• Pin-out simplifies heatsinking to the PCB
• SOURCE pins are electrically quiet for low EMI
Description
TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.
