With switching frequency as high as 500kHz, The LT1510 current mode PWM battery charger is the simplest and 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 1.5A DC current (2A peak current). The 0.1W onboard current sense resistor makes the charging current programming very simple. One resistor (or a programming current from a DAC) is required to set the full charging current (1.5A) to within 5% accuracy. The LT1510 with 0.5% reference voltage accuracy meets the critical constant-voltage charging requirement for lithium cells.
