Recently, SGMICRO launched SGM3123, a 4-channel white light driver for low-dropout mode driving small and medium-sized LCD backlight LEDs, which helps customers simplify product backlight design and reduce system cost. SGM3123 is fully compatible with SGM3122. This product can be widely used in mobile phones, GPS, consumer electronics, and SGM3123. As a new low-dropout mode white LED lamp driver, the company has done the same performance on the market. Sufficient improvement, the differential pressure is reduced to less than 90mV under 30mA current condition, which can perfectly support 4 LEDs to work stably at low battery voltage (<3.5V), working voltage is 2.5~5.5V, current error between channels is less than 5 %, can achieve higher channel brightness matching. Support PWM dimming, the recommended frequency is 200Hz ~ 10kHz, the startup time is less than 10μS (PWM frequency 200HZ), in the shutdown mode, the quiescent current is less than 1μA, which can fully meet the application of various portable products.
In addition, SGM3123 is a pollution-free and lead-free environmentally friendly product with an extended industrial temperature range from C40°C to +85°C in TQFN-16 (3×3) package for low cost solutions for charge pump version SGM3122. Alternative.
It is reported that SGM3123 has started mass production in the second quarter of 2009, and the bulk order cycle is 4-6 weeks.
