General Description

The PA5910 is a high efficiency LED driver control Integrated Circuit.

It is a universal control LED driver that can be configured to operate as a step-up or step-down LED driver.

The input and output voltage can be extended beyond 450V.

The PA5910 uses a fixed off time and 2MHz switching frequency can be achieved.

The minimum off time can be set by an external capacitor and resistor. ROFF and COFF

The LED current is programmable from 20mA to 2.0A and is set by an external resistor.
