RoHS 6 Compliant
Tiny Switch-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 fl exible solution with a low system cost and extended power capability.
Key Features
- Output Power - Adapter : 6 W
- Output Power - Open Frame : 11 W
- 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 I2f 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 fi lter costs
- Pin-out simplifi es heatsinking to the PCB
- SOURCE pins are electrically quiet for low EMI
