Intersil ISL97632IRT18Z-TK

DC DC 稳压器2.4V5.5V50mA

Overview

The ISL97632IRT18Z-TK represents an efficient and highly integrated PWM boost LED driver that is suitable for 1.8" to 3.5" LCDs that employ 2 to 7 white LEDs for backlighting. With integrated Schottky diode, OVP, and dynamic digital dimming capability, the ISL97632IRT18Z-TK provides a simple, reliable, and flexible solution to the backlight designers. The ISL97632IRT18Z-TK features a simple 1-Wire digital interface that provides a 5-bit dimming control. The dimming signal adjusts the FB voltage and therefore the LED brightness in a DC manner in 32 linear steps. An EN pin can be used to provide a zero brightness setting or shutdown power saving function. The ISL97632IRT18Z-TK is available in the 8 Ld TDFN (2mmx3mm) package. There are 14V, 18V, and 26V OVP options that are suitable for 3, 4, and 7 LEDs (3.5V/20mA type) backlight applications respectively. The ISL97632IRT18Z-TK is specified for operation over the -40°C to +85°C ambient temperature at input voltage from 2.4V to 5.5V.
