Product Description

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.
