TinySwitch-II Family

Enhanced, Energy Efﬁcient, Low Power

Off-line Switcher

Product Highlights

TinySwitch-II Features Reduce System Cost

• Fully integrated auto-restart for short circuit and open loop fault

protection – saves external component costs

Optional

UV Resistor

Output

• Built-in circuitry practically eliminates audible noise with ordinary

dip-varnished transformer

• Programmable line undervoltage detect feature prevents power

on/off glitches – saves external components

Wide-Range

HV DC Input

EN/UV

TinySwitch-II

• 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

PI-2684-021809

Better Cost/Performance over RCC & Linears

• Lower system cost than RCC, discrete PWM and other

integrated/hybrid solutions

• Cost effective replacement for bulky regulated linears

• Simple ON/OFF control – no loop compensation needed

• No bias winding – simpler, lower cost transformer

• Simple design practically eliminates rework in manufacturing

Notes:

• Ideal for cell-phone charger and PC standby applications

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).

High Performance at Low Cost

• 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

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 undervoltage threshold, which

eliminates power down glitches caused by the slow discharge of

input storage capacitors present in applications such as standby

supplies. The operating frequency of 132 kHz is jittered to

signiﬁcantly reduce both the quasi-peak and average EMI,

minimizing ﬁltering cost.

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 TinySwitch-II devices

incorporate auto-restart, line undervoltage 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
