MPQ2169B-AEC1

6V, Dual 1.4A/1.4A or 2A/0.8A, Low-I_Q, Synchronous Buck with PG and SS, AEC-Q100 Qualified

Datasheet

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 (V_IN) and generates an output voltage (V_OUT) as low as 0.6V. The MPQ2169B can be configured as a 1.4A/1.4A or 2A/0.8A output current (I_OUT) regulator, and is ideal for powering portable equipment that runs on a single-cell Li-ion battery due to its low 65μA quiescent current (I_Q).

The MPQ2169B integrates dual, 60mΩ, high-side MOSFETs (HS-FETs) and 25mΩ synchronous rectifiers (SR) 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.
