Description
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.
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.

Notes:
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.
