Product details

Description

Pin Name Description 1 HV This is the input of the high voltage startup regulator and connects directly to the bulk voltage.A constant cur- rent source supplies current from this pin to the VCC capacitor, eliminating the need for an external startup resistor.The charge current is 7.5 mA (typical).2 OSC A capacitor on this pin adjusts the frequency of the internal oscillator.The oscillator sets the frequency of the half bridge controller. bridge switch ope

Features

needed to implement a highly efficient and small form factor LED Driver/Power Supply. It contains a critical conduction mode (CrM) power factor correction (PFC) boost controller and a half.
bridge resonant controller with a built.
in 600 V driver. The half.
bridge stage operates at a fixed frequency, greatly simplifying the control implementations. The output (current or voltage) regulation is achieved by adjusting the PFC stage output voltage.
based on a control si.
