BL8082B

PMU with 1 Synchronous Buck and 2 LDOs

FEATURES

DESCRIPTION

The BL8082B is a power management unit (PMU),

with 1 synchronous Buck and 2 low-dropout

regulators that delivers a maximum current of 1A

for each individual output.

BUCK



High Efficiency : Up to 97%

Capable of Delivering 1.2A

1.5MHz Switching Frequency

No External Schottky Diode Needed

Low dropout 100% Duty operation

Internal Compensation and Soft-Start

Current Mode control

0.6V Reference for Low Output voltages

Logic Control Shutdown (IQ<1uA)

Thermal shutdown, UVLO and OVP

The synchronous buck is a high-efficiency, DC-to-

DC step-down switching regulator, capable of

delivering up to 1.2A of output current. The device

operates from an input voltage range of 2.6V to

7V and provides an output voltage from 0.6V to

VIN, making the buck ideal for low voltage power

conversions. Running at a fixed frequency of

1.5MHz allows the use of small external

components, such as ceramic input and output

caps, as well as small inductors, while still

providing low output ripples. This low noise

output along with its excellent efficiency achieved

by the internal synchronous rectifier, making the

buck an ideal green replacement for large power

consuming linear regulator. Internal soft-start

control circuitry reduces inrush current. Short-

circuit and thermal-overload protection improves

design reliability.

LDO



Maximum output current for each channel is 1A

Range of operation input voltage: Max 12V

Standby current of VO1: 2mA (typ.)

Standby current of VO2: 55uA (typ.)

Line regulation: 0.1%/V (typ.)

Load regulation: 10mV (typ.)

Compatible with tantalum capacitor, electrolytic

capacitor and MLCC.

APPLICATIONS

Each of the 2 LDOs is low-dropout regulator that

delivers a maximum current of 1A individual

output. Typical dropout voltage at 1A load current

is 1.3V. The output accuracy of each channel is set

within 2% by trimming.

Power Management for Computer Mother

Board, Graphic Card



LCD Monitor and LCD TV

DVD Decode Board

ADSL Modem

Set top boxes

Post Regulators for Switching Supplies Cellular

phones

Typical LDO output voltage: VO1=3.3V, VO2=ADJ.

Other fixed voltage (e.g 1.2V, 1.8V, 2.5V, 3.3V, 5V)

or adjustable output also can be customized on

command.

The LDO offers thermal shut down and current

limit functions to ensure reliability of device and

power system.

PIN OUT & MARKING

BL8082B is available in lead (Pb)-free DFN3X3-12

(with 2 exposed pads for heat dissipation) package.
