Product 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.
- Simple ON/OFF control, no loop compensation needed
- Selectable current limit through BP/M capacitor value
- A higher current limit extends peak power or, in open frame applications, maximum continuous power
- A lower current limit improves efficiency in enclosed adapters/chargers
- Allows optimum TinySwitch-III choice by swapping devices with no other circuit redesign
- Maximizes MOSFET and magnetics power delivery
- Minimizes max overload power, reducing the cost of the 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
