BL8519 Built-in 2A Power MOSFET Step-down DC-DC Converter DESCRIPTION BL8519 is a current mode PWM step-down DC-DC converter that has an internal 2A power switch. It has a wide input voltage range of 3.6V to 20V, which make it suitable for regulating a wide variety of power sources. BL8519 is made up of a PWM control circuit, a reference voltage unit, an error amplifier, a protection circuit, Chip Enable circuit, and under voltage lockout circuit. A low ripple high efficiency step-down DC-DC converter can be easily assembled by this IC with minimum external components: an inductor, a diode, capacitors and resistors. Desired output voltage can be achieved by adjusting the value of external resistors.
