PRIMARY SIDE CONTROL CONSTANT CURRENT POWER SWITCH
DESCRIPTION
The UL13A is a high performance primary-side controller
for low power AC/DC off-line applications. It can provide accurate
constant current regulation without the need of an opto-coupler or
reference device.
Built-in safe operation circuitry is provided such as
cycle-by-cycle current limit, output short-circuit/open-circuit
protection and soft start.
