SGM3725

38V Step-Up LED Driver

GENERAL DESCRIPTION

FEATURES

The SGM3725 is a versatile constant current LED

● Wide Output Range: Up to 10 Series LEDs

● Integrated 40V High Current Switch (1.35A Limit)

● 2.7V to 5.5V Input Voltage Range

● High Efficiency PWM Converter

● Low 200mV Feedback Voltage

driver with

high efficiency step-up converter

architecture. Unique technology and high 1.35A current

limit allow SGM3725 to drive up to 38V output (10

LEDs in series). Alternatively, SGM3725 can deliver

260mA total current with 3 series LEDs per string. It

can also maximize the current capability while

achieving high conversion efficiency. The optimized

1.1MHz switching frequency results in reduced

conduction loss and small external component size. A

single wire interface is integrated to adjust the FB

voltage in 32 steps, which can overcome audible noise

and inrush current issues in normal PWM dimming

schemes.

● 500kΩ Pull-Down Resistor on CTRL Pin

● Single Wire Dimming Interface

● 38V Open LED Protection

● 1.1MHz Switching Frequency

● Integrated Soft-Start Function

● Less than 1µA Shutdown Current

● Simple, Small Solution Size

● Available in Green TSOT-23-6 Package

● -40℃ to +85℃ Operating Temperature Range

Various protection features are built into the SGM3725,

including cycle-by-cycle input current limit protection,

open LED (output over-voltage) protection and thermal

shutdown protection. The leakage current in shutdown

mode is less than 1µA.

APPLICATIONS

LED Backlighting

Mobile Phones

Handheld Devices

Digital Photo Frames

Automotive Navigation

The SGM3725 is available in Green TSOT-23-6

package. It operates over an ambient temperature

range of -40℃ to +85℃.
