HV9911

Switch-Mode LED Driver IC with High Current Accuracy

Features

General Description

The HV9911 is an LED driver IC designed to control

single-switch PWM converters (buck, boost,

buck-boost and SEPIC) in a Constant Frequency or

Constant Off-time mode. The controller uses a peak

current control scheme with programmable slope

• Switch-mode Controller for Single-switch Drivers:

- SEPIC

compensation

and

includes

internal

transconductance amplifier to control the output current

in closed loop, enabling high output current accuracy.

In the Constant Frequency mode, multiple HV9911s

can be synchronized with each other or with an

external clock using the sync pin. Programmable

MOSFET current limit enables current limiting during

Input Undervoltage and Output Overload conditions.

The IC also includes a 0.2A source and 0.4A sink gate

driver for high-power applications. An internal

9V–250V linear regulator powers the IC, eliminating the

need for a separate power supply. The HV9911

provides a TTL-compatible 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 IC also provides a FAULT output which, can be

used to disconnect the LEDs in case of a Fault

condition, using an external disconnect FET.

• Works with High-side Current Sensing

• Closed-loop Control of Output Current

• High Pulse-Width Modulation (PWM) Dimming

Ratio

• Internal 250V Linear Regulator (can be extended

using external Zener Diodes)

• Internal 2% Voltage Reference (0°C < T_A< 85°C)

• Constant Frequency or Constant Off-time

Operation

• Programmable Slope Compensation

• Logic Input for Enable and PWM Dimming

• +0.2A/-0.4A Gate Driver

• Output Short-circuit Protection

• Output Overvoltage Protection

• Synchronization Capability

• Programmable Metal-Oxide Semiconductor

Field-Effect Transistor (MOSFET) Current Limit

The HV9911-based LED driver is ideal for RGB

backlight applications with DC inputs. HV9911-based

LED lamp drivers can achieve efficiency in excess of

90% for buck and boost applications.

Applications

• RGB Backlight Applications

• Battery-powered LED Lamps

• Other DC/DC LED Drivers
