Low dropout, constant-current/constant-voltage 3A battery charger
A low dropout, constant-current/ constant-voltage 3A battery charger is described.
The LT1511 current mode PWM battery charger is the simplest, most efficient solution for fast charging modern rechargeable batteries that require constant-current and/or constant-voltage charging including lithium-ion (Li-Ion), nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd).
Higher duty cycle for the LT1511 battery charger
Maximum duty cycle for the LT1511 constant-current/constant-voltage battery charger is typically 90%, but this may be too low for some applications. For example, if an 18V ±3% ...
