STLD20CP1

Power management for white LED and camera flash

Features

■ Inductor step-up to 17 V output for 2 to 4 white

LEDs in series from 2.8 V to 6 V supply

■ Charge pump 2X, 1X output for 1 power

flash/torch WLED

■ Control pins to select shutdown mode

■ Single-wire pulse dimming control for white

QFN16 (3x3 mm)

LED

■ External resistor to set max current up to 300

mA in flash mode

■ External resistor to set max current up to 100

mA in torch mode

suitable for battery-powered applications. It is

possible to select the value of the current flowing

through the power white LED using two external

resistors to choose the current value in torch

mode or flash mode. Single-wire pulse dimming

control and shutdown of the white LEDs for

backlighting is obtained through two digital control

pins: DM1 and DM2. The flash is driven by two

logic pins: TF, to enable the flash function, and

SEL to select torch or flash mode. Other features

include over-voltage and over-temperature

protection, and inductor current limitation. The

high efficiency of the STLD20CP1 makes it

suitable for hand-held instruments and

■ Logic input to select flash/strobe or movie/torch

mode

■ Soft start limits inrush current

■ Internally limited inductor peak current

■ Over-voltage and over-temperature protection.

■ Package: QFN16 (3x3 mm)

■ Temperature range: -40 °C to 85 °C

Description

The STLD20CP1 is a power management device

for the supply of white LED TFT backlighting

MAIN/SUB display and camera flash. It is a 1.3

MHz PWM step-up switching regulator and 2X

and 1X charge pump. The current feedback

control of the step-up provides excellent line

transient response, making it particularly

particularly ideal in mobile phones. The

STLD20CP1 is available in a small, thin low-

profile QFN16 (3x3 mm) package.
