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 (IOUT) across a wide input voltage (VIN) 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.
The EVQ7200A-L-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7200A, a constant-current LED driver with integrated power MOSFETs. It offers a compact solution to achieve 3A of continuous output current (IOUT), with excellent load and line regulation across a wide input supply range.
Constant frequency hysteretic control mode provides fast transient response without loop compensation. The switching frequency (fSW) is 410kHz in buck mode for optimized efficiency and electromagnetic interference (EMI) performance.
The MPQ7200A is available in a QFN-19 (3mmx4mm) package with wettable flanks, and is available in AEC-Q100 Grade 1. The EVQ7200A-L-00A is a fully assembled and tested buck mode LED driver evaluation board. It generates an LED current up to 3A from a 6V to 42V input range.
