TNY177PN pinout datasheet

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 efficiency in enclosed adapters/ chargers
• Allows optimum TinySwitch-LT 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 heat sinking to the PCB
