TinySwitch-III
Family
Energy Efficient, Off-Line Switcher with
Enhanced Flexibility and Extended Power Range
Figure 1. Typical Standby Application.
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
Enhanced Safety and Reliability Features
• Accurate hysteretic thermal shutdown protection with
automatic recovery eliminates need for manual reset
• Improved auto-restart delivers <3% of maximum power
in short circuit and open loop fault conditions
• Output overvoltage shutdown with optional Zener
• Line under-voltage detect threshold set using a single
optional resistor
• Very low component count enhances reliability and
enables single-sided printed circuit board layout
• High bandwidth provides fast turn on with no overshoot
and excellent transient load response
• Extended creepage between DRAIN and all other pins
improves field reliability
EcoSmart®
– Extremely Energy Efficient
• Easily meets all global energy efficiency regulations
• No-load <150 mW at 265 VAC without bias winding,
<50 mW with bias winding
• ON/OFF control provides constant efficiency down to
very light loads – ideal for mandatory CEC regulations
and 1 W PC standby requirements
Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital
cameras, MP3/portable audio, shavers, etc.

Table 1.
Notes: 1. Minimum continuous power in a typical non-
ventilated enclosed adapter measured at 50 °C ambient. Use of an
external heatsink will increase power capability 2. Minimum peak
power capability in any design or minimum continuous power in an
open frame design (see KeyApplication Considerations). 3. Packages:
P: DIP-8C, G: SMD-8C. See Part Ordering Information.
• PC Standby and other auxiliary supplies
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc.
