The MP24895A is step-down LED driver designed in continuous current mode for driving the high-brightness LEDs from a wide input voltage of 6V to 36V. The MP24895A employs a hysteretic control scheme to regulate the LED current. This control scheme provides optimal loop stabilization and a very quick response time. For high accuracy, the MP24895A senses the LED current by an external high-side resistor. Its low 100mV average feedback voltage reduces power loss and improves efficiency. The MP24895A implements pulse-width modulation (PWM) and analog dimming on EN/DIM. Full protection features include under-voltage lockout (UVLO) and thermal overload protection to prevent damage in the event of an output overload. The MP24895A is available in an MSOP-8 EP package.
The EV24895-J-00A is an evaluation board for the MP24895GJ, a step-down converter designed in hysteretic current control mode for driving the high brightness LEDs from wide input voltage of 9V to 30V.
The MP24895 employs hysteretic control architecture to regulate LED current. Moreover, this control scheme provides optimal circuit stabilization and a very quick response time without loop compensation. The highly accurate LED current is measured through an external high-side current-sense resistor. Its low 100mV average feedback voltage reduces power loss and improves the efficiency.
The MP24895 implements PWM and analog dimming together on the EN/DIM pin. The MP24895 includes under-voltage lockout, and thermal overload protection to prevent damage in the event of an output overload.
