AP2813 is a dual buck constant current driver, high efficiency, simple peripheral, built-in power management for
high-precision constant current LED driver core buck 5-80V input
sheet. Built-in power tube maximum output power up to 12W,
maximum current of 1.2A.
AP2813 way straight on, all the way through the addition
MODE1 switching all light, strobe. AP2813 working
frequency is fixed at about 150KHZ, while internal frequency jitter
circuit to reduce EMI interference to other devices.
Further uses average current-mode sampling can improve a wide
current accuracy in input voltage.
AP2813 with an output short circuit protection,
under the condition of 5V ~ 80V input, short-term short circuit will not damage
the power device.
There AP2813 current over temperature regulation.
When the internal temperature of the chip reaches about 140 ℃, it will
automatically reduce the output current.
