TNY178PN DIP7

TNY178PN DIP7  

Lowest System Cost with Enhanced Flexibility

• 650 V rating optimized for non-active PFC applications

• 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-LT 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
