A Circuit for charging NiCd, NiMH and Lithium-Ion Batteries.PWM 500kHz with Soft Start and Shutdown Control. The LT1510 can charge batteries ranging from 2V to 20V. Ground sensing of current is not required and the battery’s negative terminal can be tied directly to ground. A saturating switch running at 200kHz (500kHz for LT1510-5) giveshigh charging efficiency and small inductor size.
