Advanced Protection/Safety Features

• Auto-restart protection reduces power delivered by >95% for

output short circuit and control loop faults (open and shorted

components)

• Hysteretic thermal shutdown – automatic recovery reduces

power supply returns from the ﬁeld

• Meets high voltage creepage requirements between DRAIN and

all other pins both on the PCB and at the package

more information).

• Easily meets all global energy efﬁciency regulations

• No-load consumption below 30 mW at 230 VAC with optional

external bias winding

• ON/OFF control provides constant efﬁciency down to very light

loads – ideal for CEC and ENERGY STAR 2.0 regulations

• No current sense resistors – maximizes efﬁciency

Description

Notes:

The LinkSwitch-II dramatically simpliﬁes low power CV/CC

charger designs by eliminating an optocoupler and secondary

control circuitry. The device introduces a revolutionary control

technique to provide very tight output voltage and current

regulation, compensating for transformer and internal parameter

tolerances along with input voltage variations.

1. Minimum continuous power in a typical non-ventilated enclosed adapter

measured at +50 °C ambient, device, T_J<100 °C.

2. Maximum practical continuous power in an open frame design with adequate

heatsinking, measured at 50 °C ambient (see Key Applications Considerations

section for more information).

3. Packages: P: DIP-8C, G: SMD-8C, D: SO-8C.

The device incorporates a 700 V power MOSFET, a novel ON/OFF

control state machine, a high voltage switched current source for

self biasing, frequency jittering, cycle-by-cycle current limit and

hysteretic thermal shutdown circuitry onto a monolithic IC.
