TPS62040DRCR

The TPS62040DRCR is a kind of high efficiency synchronous step-down dc-dc converter which is optimized for battery powered portable applications. It is ideal for portable applications powered by a single Li-Ion battery cell or by 3-cell NiMH/NiCd batteries. With an output voltage range from 6.0 V down to 0.7 V, TPS62040DRCR supports low voltage DSPs and processors in PDAs,pocket PCs, as well as notebooks and subnotebook computers.

Features of the TPS62040DRCR are:(1)up to 95% conversion efficiency; (2)typical quiescent current: 18 A; (3)load current: 1.2 A; (4)operating input voltage range: 2.5 V to 6.0 V; (5)switching frequency: 1.25 MHz; (6)adjustable and fixed output voltage; (7)power save mode operation at light load currents; (8)100% duty cycle for lowest dropout; (9)internal softstart; (10)dynamic output voltage positioning; (11)thermal shutdown; (12)short-circuit protection; (13)10 pin MSOP powerpad. package; (14)10 pin QFN 3 X 3 mm package.

The absolute maximum ratings of the TPS62040DRCR can be summarized as:(1): supply voltage VIN  is -0.3 V to 7 V; (2): voltages on EN, MODE, FB, SW is -0.3 V to VCC +0.3 V; (3): operating junction temperature range  is -40°C to 150°C; (4): storage temperature range  is -65°C to 150°C; (5): lead temperature (soldering, 10 sec) is 260°C.
