BL8516

DESCRIPTION BL8516 is a current mode PWM step-down DC-DC converter, which has an internal 2A power switch. It has the wide input voltage range of 3.6V to 20V, so it can suit for regulating a wide variety of power source. BL8516 use bipolar technology and make 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 composed of this IC with only several external components, or an inductor, a diode and capacitors. Output Voltage can be adjusted with external resistors. The BL8516 has the cycle-by-cycle current limit circuit; current limiting provides protection against shorted output. The low current (<1uA) shutdown provides complete output disconnect, enabling easy power management in battery powered systems.
