MPQ7200A-AEC1

42V, 1.2A Buck-Boost or 3A Buck, 410kHz with FSS, Synchronous LED Driver, AEC-Q100 Qualified

Datasheet

Description

The MPQ7200A is a fixed-frequency, constant-current, buck-boost LED driver with integrated power MOSFETs. It offers a compact solution that can achieve up to 1.2A of continuous output current (I_OUT) across a wide input voltage (V_IN) range, with excellent load and line regulation. The MPQ7200A can also be configured for buck mode to provide up to 3A of continuous load current.

Constant-frequency hysteretic control mode provides extremely fast transient response without loop compensation. Full protection features include over-current protection (OCP), output over-voltage protection (OVP), under-voltage protection (UVP), thermal derating, and thermal shutdown (TSD). The fault indicator outputs an active logic-low signal if a fault occurs.

The MPQ7200A requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-19 (3mmx4mm) package.
