Datasheet

Boost LED Driver

Brief Description

Features

The ZSLS7025, one of our ZSLS Family of LED

control ICs, is a constant current boost converter

designed for driving high-brightness LEDs. It is

optimal for driving multiple white LEDs connected

in series so that the LED current is uniform for

better brightness and color control. The wide input

range and high output current enables diverse

industrial, after-market automotive, and consumer

lighting applications.

• Wide application input voltage range: 5V to

100V (Higher voltage supported. See section

2.1 in the data sheet.)

• Constant current output limited only by

external component selection

• No loop compensation required

• Internal over-voltage protection

• Internal over-temperature protection

• Brightness control via PWM or DC voltage

control signal input

The ZSLS7025 output current is adjustable via an

external current sense resistor and can deliver

• SOP-8 package

stable constant output current from

milliamps up to 2A or higher.

Benefits

The ZSLS7025 drives a constant current into the

load. The control loop features a pulse frequency

modulated (PFM) architecture that is inherently

stable and does not need loop compensation.

• High efficiency: up to 95%

• Minimum bill of materials

• Small form-factor package

The ZSLS7025 supports pulse-width modulation

(PWM) or linear voltage dimming, which allows

flexible control of the LED luminance.

Available Support

The ZSLS7025 can operate in applications with a

wide input voltage range from 5V to 100V. An

integrated over-voltage protection (OVP) circuit

protects the system, even under no-load

conditions. The over-voltage protection is

adjustable via external resistors R₁and R₂.
