About This Product

■Summary

The MP23701 is a 24V, monolithic, synchronous, step-down white LED driver with integrated power MOSFET and rectifier. The MP23701 can achieve up to 2A continuous output current with excellent load and line regulation. Peak current mode operation provides fast transient response and easy loop stabilization. MP23701 implements deep analog dimming. Extensive protection features include cycle-by-cycle peak current limiting, output short-circuit protection (SCP), open LED protection, NTC thermal protection, and thermal shutdown. The MP23701 requires a minimal number of standard off-the-shelf external components and is offered in a UTQFN-8 (1.5mm x 2.5mm) package.

■Features and benefits

・Wide input range from 4.2V to 24V ・Synchronous rectification step-down converter ・100mΩ internal high-side power switch ・80mΩ internal low-side synchronous rectifier ・Peak current mode control ・Continuous output current up to 2A ・100mV feedback voltage ・Up to 97% efficiency ・Fixed 1.5MHz switching frequency ・Analog dimming ・Current limit per cycle ・Unique LED open protection ・Output short circuit protection (SCP) ・NTC thermal protection ・Thermal shutdown ・Auto restart function ・Provided in UTQFN-8 (1.5mm x 2.5mm) package

■Available product numbers

・MP23701GQEU-P MP23701GQEU-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
