Product Details
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 enclosedadapters/chargers
- Allows optimumTinySwitch-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 heatsinking to the PCB
• SOURCE pins are electrically quiet for low EMI
