STLED25 Datasheet | STMicroelectronics

5 channels step-up white LED driver - production data Features - Operating input voltage range from 2.3 V to 5.5 V - ± 7.5% LED current accuracy - Two LEDs in series per channel - High side current source - Up to 125 m A of total LED current - 86% efficiency at 100 m A - PWM dimming with automatic shutdown time window - 2.5 MHz switching frequency - CSP 12 bumps 0.4 mm. pitch 1.4 x 1.8 mm. Applications - LCD backlight with up to 10 LEDs - Cellular phones - PDAs Description Flip-Chip 12 bumps (1.4 x 1.8 mm.) continue operating driver channels that are functioning normally, while avoiding excessive power consumption or associated thermal issues. The control technique is able to maintain the efficiency close to 87% at medium load and higher than 85% at light or full load. The device also includes soft-start control, inrush current limit, thermal shutdown and inductor peak current limit. The STLED25 is packaged in a 12-bump CSP (1.4 x 1.8...
