DESCRIPTION

· The PS30 LED driver IC is designed for dimmable LED bulbs, tubes, and similar lighting applications.

· It operates in non-isolated buck-boost or isolated buck-boost (flyback) topology in discontinuous conduction mode.

· Uses constant switching frequency and duty for high power factor operation.

· Adjusts switch duty to compensate for line voltage and inductance variations.

· Compatible with leading edge, trailing edge, and two-wire digital dimmers.

FEATURES

· Compatible with various dimmers including leading edge, trailing edge, and two-wire digital dimmers.

· Suitable for isolated and non-isolated configurations.

· Features simple open loop controls with fixed line voltage design.

· Mimics incandescent bulb behavior with constant frequency and duty switching.

· Operates in discontinuous current mode with high power factor.

· No frequency compensation required, switches at 67 kHz.

· Resistor programmed duty/ON time, adjusts for line voltage and inductance variations.

· LED power regulation accuracy of ±2%, LED current accuracy ±4% (typ), and LED current line regulation ±3% (typ).

APPLICATIONS

· General Lighting.

· Dimmable Light Fixtures.

· Dimmable Bulb/Tube Replacement.
