■ The LT®1511 current mode PWM battery charger is the
simplest, most efficient solution to fast charge modern
rechargeable batteries including lithium-ion (Li-Ion), nickelmetal-hydride (NiMH) and nickel-cadmium (NiCd) that
require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 3A* DC
current (4A peak current). Full-charging current can be
programmed by resistors or a DAC to within 5%. With 0.5%
reference voltage accuracy, the LT1511 meets the critical
constant-voltage charging requirement for Li-Ion cells. Simple Design to Charge NiCd, NiMH and Lithium
Rechargeable Batteries—Charging Current
