Monolithic Power Systems MPQ7200A | Demoboard EVQ7200A-L-00B

Description

The EVQ7200A-L-00B is an evaluation board designed to demonstrate the capabilities of the MPQ7200A, a constant-current LED driver with integrated power MOSFETs. It offers a very compact solution to achieve 1.2A of continuous output current (IOUT), with excellent load and line regulation across a wide input supply range.Constant frequency hysteretic control mode provides extremely fast transient response without loop compensation. The switching frequency (fSW) is 410kHz in buck-boost mode for optimized efficiency and thermal 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-00B is a fully assembled and tested buck-boost mode LED driver evaluation board. It generates an LED current up to 1.2A from a 6V to 20V input range.
