BL8076
2A 3MHz 6V Synchronous Buck Converter
DESCRIPTION
The BL8076 is a high efficiency synchronous, buck
DC/DC converter. Its input voltage range is from
2.6V to 6V and provides an adjustable regulated
output voltage from 0.6V to Vin while delivering
up to 2A of output current.
The internal synchronous switches increase
efficiency and eliminate the need for an external
Schottky diode. It runs at a fixed 3MHz frequency,
which allows the use of small inductor with
L<1uH while maintaining a high efficiency and
small output voltage ripple.
When Mode pin is connected to Gnd, the BL8076
is operating in PFM/PWM auto-switch mode
which enhance the efficiency at light-load.
The BL8076 is available in DFN2x2-8L and SOT23-5
packages.
