G5997

Global Mixed-mode Technology

Step-up Controller for 12 Strings 60mA White LED Driver

General Description

Features

5V~30V input voltage range

The G5997 is current mode DC/DC controller that

drives up to 12 strings connected in parallel configura-

tion with multiple LEDs in each string connected in se-

ries. External current sense resistor and slope com-

pensation resistor make it flexible for various applica-

tions. PWM dimming is implemented with external

PWM input signal or DC input signal. The dimming fre-

quency can be programmed by an external setting ca-

pacitor.

High Power Current Mode DC/DC boost

Controller

Drives up to 12 strings in parallel

100Hz~2KHz PWM or DC Input True PWM Dim-

ming

2.5% Current Matching Accuracy Between

Strings

Programmable Switching Frequency

Input Under Voltage Protection

Output Short Circuit Protection

Hiccup Mode Protection for Output Over Voltage

Protection and LED String Short Protection

Thermal Shutdown

The G5997 includes hiccup protection from short cir-

cuits, with automatic recovery after the fault condition is

cleared.

Available in SOP-28, TSSOP-28 (FD) and

TQFN5X5-28 Package
