BL8516 BL8516 的详细介绍

BL8516 BL8516is 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.
