MP2101

1.6MHz Synchronous Step-Down

plus 200mA LDO

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2101 is an internally compensated

1.6MHz fixed-frequency PWM step-down

switcher with a 200mA low dropout (LDO) linear

regulator. It is ideal for portable equipment

Battery. The MP2101 can provide 800mA and

200mA of load current from a 2.5V to 6V input

voltage. Both output voltages can be regulated

as low as 0.6V.

•

0.8A Switcher Output and 0.2A LDO Output

V_IN1Range for Switcher: 2.5V to 6V

V_IN2Range for LDO: 1.2V to V_IN1

Internal Power MOSFET Switches

Stable with Low ESR Output Ceramic

Capacitors

•

Up to 93% Efficiency

0.01µA Shutdown Current

1.6MHz Fixed Switching Frequency

Up to 100% Switcher Duty Cycle

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Short Circuit Protection

The 800mA output channel features an

integrated high-side switch and synchronous

rectifier for high efficiency without an external

Schottky diode. With peak current mode control

and internal compensation, the MP2101 can be

stabilized with ceramic capacitors and small

inductors. The high-side switch can maintain

100% duty cycle in dropout condition.

Power On Reset Output

Available in 3x3 10-Pin QFN Packages

APPLICATIONS

•

DVD+/-RW Drives

Smart Phones

PDAs

Digital Cameras

Portable Instruments

The 200mA LDO output is used to power noise

sensitive circuitry. It has a separate input supply

to reduce power dissipation and noise from the

main switcher. Dropout voltage is 280mV under

a 150mA load. Fault condition protection

includes cycle-by-cycle current limiting and

thermal shutdown.

The MP2101 is available in small 3mm x 3mm

10-pin QFN packages.
