Full light semi-bright strobe IC LED constant current chip Buck

AP2403 is a PWM mode of operation, high efficiency, simple peripheral, built-in power management, input 5-100V for high
precision constant current LED driver chips down. The maximum output power up to 22W, maximum current of 2.2A.
AP2403 switching function can be implemented three sections, by MODE1 / 2/3 switching three functional modes: full bright, semi-bright, flash explosion
.
AP2403 operating frequency is fixed at about 150KHZ, while internal frequency jitter circuit to reduce EMI to other devices
interference. Further uses average current-mode sampling, current accuracy can be improved under a wide input voltage.
AP2403 with an output short circuit protection, under the condition of 5V ~ 100V input, without damaging the short short-circuit power devices.
There AP2403 current over temperature regulation. When the internal temperature of the chip reaches about 140 ℃, it will automatically reduce the output
stream. Features Applications
