TPS62410

The TPS62410 device is a synchronous dual step-down DC-DC converter optimized for battery powered portable applications. It provides two independent output voltage rails powered by 1-cell Li-Ion or 3-cell NiMH/NiCD batteries.

Features of the TPS62410 are:(1)high efficiency-up to 95%;(2)VIN range from 2.5 V to 6 V;(3)2.25 MHz fixed frequency operation;(4)output current 2 and 800 mA;(5)adjustable output voltage from 0.6V to VIN;(6)pin selectable output voltage supports simple dynamic voltage scaling;(7)easyscale optional one-pin serial interface;(8)power save mode at light load currents;(9)180° out of phase operation;(10)output voltage accuracy in PWM mode ±1%;(11)typical 32-mA quiescent current for both converters;(12)100% duty cycle for lowest dropout;(13)available in a 10-Pin QFN (3*3mm).
