■ The LT®1769 current mode PWM battery charger is a
simple, efficient solution to fast charge modern rechargeable batteries including lithium-ion (Li-Ion), nickel-metalhydride (NiMH) and nickel-cadmium (NiCd) that require
constant-current and/or constant-voltage charging. The
internal switch is capable of delivering 2A** DC current
(3A peak current). Charge current can be programmed by
resistors or a DAC to within 5%. With 0.5% reference voltage
accuracy, the LT1769 meets the critical constant-voltage
charging requirement for Li-Ion cells. Simple Solution to Charge NiCd, NiMH and Lithium
Rechargeable Batteries—Charging Current
