Monolithic Power Systems (MPS) MP7230 Infrared LED Drivers introduce a fixed-frequency, constant current, buck-boost device built for integrated power MOSFETs. The MP7230 supplies 1.2A of continuous output current in a very compact solution, with exceptional load and line regulation spanning a wide input supply range. The MP7230 buck mode allows configurability with up to 3A of constant load current. The MP7230 supports PWM dimming frequencies as low as 10Hz to adjust infrared radiation (IR) in LED driver applications. The device is also compatible with 30FPS, 60FPS, and 120FPS dimming.
Constant frequency hysteretic control mode supplies an extremely fast transient response without loop compensation. The device’s full protection features include over-current protection (OCP), thermal derating (TD), and thermal shutdown (TSD).
The MP7230 comes in a space-saving QFN-19 (3mm x 4mm) package and requires a minimal number of standard external components.
