HV9963

Closed Loop LED Driver with Enhanced PWM Dimming

Features

General Description

► Switch mode controller for single switch converters

The HV9963 is a current mode control LED driver IC designed

to control single switch PWM converters (buck, boost,

buck-boost or SEPIC) in a constant frequency mode. The

controller uses a peak current-mode control scheme (with

programmable slope compensation) and includes an internal

transconductance ampliﬁer to accurately control the output

current over all line and load conditions. Multiple HV9963s

can be synchronized to each other or to an external clock

using the SYNC pin. The IC also provides a disconnect switch

gate drive output, which can be used to disconnect the LEDs

in case of a fault condition using an external disconnect

FET. The 10V external FET drivers allow the use of standard

level FETs. The low voltage 5.0V AVDD is used to power the

internal logic and also acts as a reference voltage to set the

current level.

● Buck

● Boost

● Buck-boost and SEPIC

► High output current accuracy

► High PWM dimming ratio (>5000:1)

► Internal 40V linear regulator

► Internal ±2% voltage reference

► Constant frequency operation with sync capability

► Programmable soft start

► 10V GATE drivers

► Hiccup mode protection for both short circuit and

open circuit conditions

Applications

TheHV9963includesanenhancedPWMdimminglogic(patent

pending) that enables very high PWM dimming ratios.

► RGB or white LED backlighting

► Battery powered LED lamps

► Other DC/DC LED drivers

HV9963 also provides a TTL compatible, 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 tens of

kilohertz.
