Description
The TinySwitch-III family of offline switchers are designed for low-power offline applications, providing integrated features such as a power MOSFET, oscillator, PWM control, and protection circuitry in a single chip. These ICs are commonly used in power supply applications for consumer electronics, appliances, LED lighting, and other low-power systems.
The TNY180PN offers benefits such as high efficiency, low standby power consumption, and compact size. It incorporates Power Integrations’ EcoSmart technology to optimize energy usage and enable compliance with various energy efficiency standards.
It integrates a 650V MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single package, simplifying design and reducing component count.
Pinout and Block Diagram
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
• 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
Applications
1. AC-DC Adapters: For consumer electronics and home appliances.
2. Standby Power Supplies: For devices requiring low standby power consumption.
3. Auxiliary Power Supplies: In industrial and automation systems.
