The MP7230 is a fixed-frequency, constant-current, buck-boost LED driver with integrated power MOSFETs. The device offers a compact solution that can achieve up to 1.2A of continuous output current (IOUT) across a wide input voltage (VIN) supply range, with excellent load and line regulation. The MP7230 can also be configured to buck mode to provide up to 3A of constant load current.
The MP7230 can support pulse-width modulation (PWM) dimming frequencies as low as 10Hz to adjust infrared radiation (IR) in LED driver applications. It is also compatible with 30FPS, 60FPS, and 120FPS dimming. Constant frequency hysteretic control mode provides extremely fast transient response without loop compensation.
Full protection features include over-current protection (OCP), thermal derating, and thermal shutdown (TSD). The MP7230 requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-19 (3mmx4mm) package.
