AP2401 built-in MOS_two-function buck constant current drive fog lamp version

Product Description:

AP2401 is a PWM working mode, high efficiency, simple peripherals, built-in power tube, suitable for 5-100V input high-precision step-down LED constant current driver chip. The maximum output power can reach 10W, and the maximum current is 1A.

AP2401 can realize two-stage function switching, and switch between two function modes through MODE2/3: full bright, half bright, full bright/half bright/burst flash cycle mode.

The working frequency of AP2401 is fixed at about 150KHZ, and the built-in frequency jitter circuit can reduce EMI interference to other equipment. In addition, the average current sampling mode can be used to improve current accuracy under wide input voltage conditions.

Features:

Wide input voltage range: 5V～100V

Settable current range: 10mA～1000mA

Fixed working frequency: 150KHZ

Built-in frequency jitter circuit to reduce EMI interference to other equipment
