The MP2410GJ-Z from Monolithic Power Systems is a highly integrated synchronous step-down white LED driver supporting a 4.2V to 24V input range and up to 2A of continuous LED output current. Peak-current-mode control provides fast transient response while simplifying loop stabilization.
The device integrates both a high-side power MOSFET and a low-side synchronous rectifier. At VIN=5V, typical RDS(on) is 100mΩ for the high-side MOSFET and 80mΩ for the low-side switch. This synchronous architecture enables conversion efficiency of up to 97% while reducing the need for external rectification components.
The MP2410 operates at a fixed 1MHz switching frequency and uses a typical 100mV feedback reference for LED current regulation. The low feedback voltage helps reduce current-sense resistor losses, while the high switching frequency supports compact inductors and capacitors.
An integrated EN/DIM input provides enable control and analog dimming. Typical analog-dimming thresholds range from approximately 0.7V to 1.44V. Typical quiescent current is 0.9mA, while typical shutdown current is only 10µA.
Protection features include cycle-by-cycle current limiting, inherent LED open protection, output short-circuit protection, over-current protection, thermal shutdown and automatic restart. These functions help protect both the driver and LED load during abnormal operating conditions.
The exact MP2410GJ-Z ordering option uses a compact 6-pin TSOT23-6 package. MPS specifies the -Z suffix for tape-and-reel packaging. Recommended operating junction temperature is -40°C to +125°C, and MPS identifies its parts as lead-free, halogen-free and RoHS compliant.
