DESCRIPTION

The MPQ2169B is an internally compensated,

dual, pulse-width modulation (PWM),

synchronous step-down regulator that operates

from a 2.7V to 6V input voltage (VIN) and

generates an output voltage (VOUT) as low as

0.6V. The MPQ2169B can be configured as a

1.4A/1.4A or 2A/0.8A output current (IOUT)

regulator, and is ideal for powering portable

equipment that runs on a single-cell Li-ion

battery due to its low 65μA quiescent current

(IQ).

The MPQ2169B integrates dual, 60mΩ, highside

MOSFETs (HS-FETs) and 25mΩ

synchronous rectifiers to achieve high efficiency

without an external Schottky diode. The

MPQ2169B offers peak current mode control

and internal compensation, and is capable of

low-dropout configurations. Both channels can

operate at 100 duty cycle.

Full protection features include cycle-by-cycle

current limiting and thermal shutdown.

The MPQ2169B requires a minimal number of

readily available, standard external

components, and is available in a QFN-18

(2.5mmx3.5mm) package.
