Product Overview:
AP8851 is an integrated output current can be set with a step-down switching constant voltage driver IC, can be continuous output current over a wide input voltage range, and has excellent linearity adjustment of the load.
AP8851 output current can be set by an external resistor sampling precision. Chip comes with every cycle peak current limiting, internal soft-start and thermal protection.
AP8851 only needs very little conventional peripheral devices.
Using SOP8 package.
AP8851 high voltage 90V input, 0.8V reference, perfect short-circuit protection circuit. Support low voltage input 12V ~ 24V, 6-8A large current output. Support high-voltage input 48V ~ 75V, 1.5A output perfect support. It can be widely used in electric vehicles, electric bicycles, car batteries, shilly car, truck power applications
