Initial Release

HV9931 Unity Power Factor LED Lamp Driver

Features

General Description

ꢀ

Constant Output Current

The HV9931 is a ﬁxed frequency PWM controller IC designed

to control an LED lamp driver using a single-stage PFC

buckboost-buck topology. It can achieve a unity power factor

and a very high step-down ratio that enables driving a single

high-brightness LED from the 85-264VAC input without a

need for a power transformer. This topology allows reducing

the ﬁlter capacitors and using non-electrolytic capacitors to

improve reliability. The HV9931 uses open-loop peak current

control to regulate both the input and the output current. This

control technique eliminates a need for loop compensation,

limits the input inrush current, and is inherently protected

from input under-voltage condition. Capacitive isolation

protects the LED Lamp from failure of the switching MOSFET.

HV9931 provides a low-frequency PWM dimming input that

can accept an external control signal with a duty ratio of 0-

100% and a frequency of up to a few kilohertz. The PWM

dimming capability enables HV9931 phase control solutions

that can work with standard wall dimmers.
