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 effi ciency 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 fi lter costs Pin-out simplifi es heatsinking to the PCB SOURCE pins are electrically quiet for low EMI

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 effi ciency 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 fi lter costs
Pin-out simplifi es heatsinking to the PCB
SOURCE pins are electrically quiet for low EMI
