BL8516 Datasheet, PDF (1/7 Pages) SHANGHAI BELLING CO., LTD. – 1.2A Step-down DC-DC Converter

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.
