TPS7510x Low Dropout, Two-Bank LED Driver With PWM Brightness Control

1 Features

3 Description

The TPS7510x linear low dropout (LDO) matching

LED current source is optimized for low-power

keypad and navigation pad LED backlighting

applications. The device provides a constant current

to up to four unmatched LEDs organized in two banks

of two LEDs each in a common-cathode topology.

Without an external resistor, the current source

defaults to a factory-programmable, preset current

level with ±0.5% accuracy (typical). An optional

external resistor can be used to set initial brightness

to user-programmable values with higher accuracy.

Brightness can be varied from off to full brightness by

inputting a pulse width modulation (PWM) signal on

each enable pin (ENx, where x indicates LED bank A

or B). Each bank has independent enable and

brightness control, but current matching is done to all

four channels concurrently. The input supply range is

ideally suited for single-cell Li-Ion battery supplies

and the TPS7510x can provide up to 25 mA per LED.

•

Regulated Output Current with 2% LED-to-LED

Matching

•

Drives Up to Four LEDs at 25 mA Each in a

Common Cathode Topology

28-mV Typical Dropout Voltage Extends Usable

Supply Range in Li-Ion Battery Applications

•

Brightness Control Using PWM Signals

Two 2-LED Banks With Independent Enable and

PWM Brightness Control per Bank

•

No Internal Switching Signals—Eliminates EMI

Default LED Current Eliminates External

Components

–

Default Values from 3 mA to 10 mA (in 1-mA

Increments) Available Using Innovative Factory

EEPROM Programming

–

Optional External Resistor can be Used for

High-Accuracy, User-Programmable Current

No internal switching signals are used, eliminating

troublesome electromagnetic interference (EMI). The

TPS7510x is offered in an ultra-small, 9-ball, 0.4-mm

ball-pitch wafer chip-scale package (WCSP) and a

2.50-mm × 2.50-mm, 10-pin WSON package, yielding

a very compact total solution size ideal for mobile

handsets and portable backlighting applications. The

device is fully specified over T_J= –40°C to +85°C.
