S
-
-
-
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

Maximizes MOSFET and magnetics power delivery  
Minimizes max overload power, reducing cost of  
transformer, primary clamp & secondary components  
OUTPUT POWER TABLE  
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

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.

•
•
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  
•
•
•
PC Standby and other auxiliary supplies  
DVD/PVR and other low power set top decoders  
Supplies for appliances, industrial systems, metering, etc.  
•
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
