Product Description



TNY278PN Power Management IC Energy Efficient, Off-Line Switcher with Enhanced Flexibility and Extended Power Range


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 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 filter costs

• Pin-out simplifies heatsinking to the PCB

• SOURCE pins are electrically quiet for low EMI
