LinkSwitch-LP

Energy Efﬁcient Off-Line Switcher IC for

Linear Transformer Replacement

Product Highlights

Output

Lowest System Cost and Advanced Safety Features

•

Lowest component count switcher

Very tight parameter tolerances using proprietary IC

trimming technology and transformer construction

techniques enable Clampless™designs – decreases

component count/system cost and increases efﬁciency

Meets industry standard requirements for thermal overload

protection – eliminates the thermal fuse used with linear

transformers or additional components in RCC designs

Frequency jittering greatly reduces EMI – enables low cost

input ﬁlter conﬁguration

Meets HV creepage requirements between DRAIN and all

other pins, both on the PCB and at the package

Proprietary E-Shield™ transformer eliminates Y-capacitor

Rated Output Power = V_R• I_R

Superior Performance over Linear and RCC

•

Hysteretic thermal shutdown protection – automatic

recovery improves ﬁeld reliability

•

Universal input range allows worldwide operation

Auto-restart reduces delivered power by >85% during

short circuit and open loop fault conditions

(b)

PI-3924-011706

•

Simple ON/OFF control, no loop compensation needed

High bandwidth provides fast turn on with no overshoot

and excellent transient load response

Notes:

1. Output power may be limited by speciﬁc application parameters

including core size and Clampless operation (see Key Application

Considerations).

2. Minimum continuous power in a typical non-ventilated enclosed

adapter measured at 50 °C ambient.

3. Minimum practical continuous power in an open frame design with

adequate heat sinking, measured at 50 °C ambient.

4. Packages: P: DIP-8B, G: SMD-8B, D: SO-8C. For lead-free

package options, see Part Ordering Information.
