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 continuous power in an open frame design (see Key Applications
Considerations).
3. Packages: P: DIP-8C, G: SMD-8C. Lead free only. See Part Ordering
Information.
Product Highlights
Lowest System Cost with Enhanced Flexibility
Simple ON/OFF control, no loop compensation needed
Unique Peak Mode feature extends power range without
increasing transformer size
Maximum frequency and current limit boosted at peak loads
Selectable current limit through BP/M capacitor value
Higher current limit extends maximum power in open frame
Lower current limit improves efciency in enclosed adapters
Allows optimum TinySwitch-PK 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 – typically extends low line regulation range/
hold-up time to reduce input bulk capacitance
Self-biased: no bias winding required for TNY375-376; winding
required for TNY377-380
Frequency jittering reduces EMI lter costs
Optimized pin out eases pcb/external heatsinking
Quiet source-connected heatsink pins for low EMI
Enhanced Safety and Reliability Features
Accurate hysteretic thermal shutdown with automatic recovery
provides complete system level overload protection and
eliminates need for manual reset
Auto-restart delivers <3% maximum power in short circuit and
open loop fault conditions
Output overvoltage shutdown with optional Zener
Line undervoltage detect threshold set using a single 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
eld reliability
EcoSmart
– Extremely Energy Efcient
Easily meets all global energy efciency regulations
No-load <170 mW at 265 VAC without bias winding, <60 mW
with bias winding
ON/OFF control provides constant efciency down to very light
loads – ideal for mandatory CEC efciency regulations and 1 W
PC standby requirements
Applications
Applications with high peak-to-continuous power demands –
DVDs, PVRs, active speakers (e.g. PC audio), audio ampliers,
modems, photo printers
Applications with high power demands at startup (large output
capacitance or motor loads) - PC standby, low voltage motor
drives
Description
TinySwitch-PK incorporates a 700 V MOSFET, oscillator, high-
voltage switched current source, current limit (user selectable),
and thermal shutdown circuitry. A unique peak mode feature
boosts current limit and frequency for peak load conditions. The
boosted current limit provides the peak output power while the
increased peak mode frequency ensures the transformer can be
sized for continuous load conditions rather than peak power
demands.
