TinySwitch-II Family

Enhanced, Energy Efﬁcient,

Low Power Off-line Switcher

Product Highlights

DC Output

TinySwitch-II Features Reduce System Cost

Optional

UV Resistor

•

Fully integrated auto-restart for short circuit and open

loop fault protection – saves external component costs

Built-in circuitry practically eliminates audible noise with

ordinary dip-varnished transformer

Programmable line under-voltage detect feature prevents

power on/off glitches – saves external components

Frequency jittering dramatically reduces EMI (~10 dB)

– minimizes EMI ﬁlter component costs

132 kHz operation reduces transformer size – allows use

of EF12.6 or EE13 cores for low cost and small size

Very tight tolerances and negligible temperature variation

on key parameters eases design and lowers cost

Lowest component count switcher solution

Table 1. Notes: 1. Minimum continuous power in a typical

non-ventilated enclosed adapter measured at 50 °C ambient.

2. Minimum practical continuous power in an open frame

design with adequate heat sinking, measured at 50 °C

ambient (See Key Applications Considerations). 3. Packages:

P: DIP-8B, G: SMD-8B. For lead-free package options, see Part

No load consumption <50 mW with bias winding and

<250 mW without bias winding at 265 VAC input

Meets California Energy Commission (CEC), Energy

Star, and EU requirements

Ideal for cell-phone charger and PC standby applications

High Performance at Low Cost

TinySwitch-II devices incorporate auto-restart, line under-

voltage sense, and frequency jittering. An innovative design

minimizes audio frequency components in the simple ON/OFF

control scheme to practically eliminate audible noise with

standard taped/varnished transformer construction. The fully

integrated auto-restart circuit safely limits output power during

fault conditions such as output short circuit or open loop,

reducing component count and secondary feedback circuitry

cost. An optional line sense resistor externally programs a line

High voltage powered – ideal for charger applications

High bandwidth provides fast turn on with no overshoot

Current limit operation rejects line frequency ripple

Built-in current limit and thermal protection improves

safety

Description

TinySwitch-II integrates a 700 V power MOSFET, oscillator,

high voltage switched current source, current limit and

thermal shutdown circuitry onto a monolithic device. The

start-up and operating power are derived directly from

the voltage on the DRAIN pin, eliminating the need for

a bias winding and associated circuitry. In addition, the
