DESCRIPTIO
General Purpose Charger Controller High Conversion Efficiency: Up to 96% Output Currents Exceeding 4A ±0.8% Voltage Accuracy AC Adapter Current Limiting Maximizes Charge Rate* Thermistor Input for Temperature Qualified Charging Wide Input Voltage Range: 6V to 28V Wide Output Voltage: 3V to 28V 0.5V Dropout Voltage; Maximum Duty Cycle: 98% Programmable Charge Current: ±4% Accuracy Indicator Outputs for Charging, C/10 Current Detection, AC Adapter Present, Input Current Limiting and Faults Charging Current Monitor Output Available in a 20-Pin Narrow SSOP Package
The LTC®4008 is a constant-current/constant-voltage charger controller.

The PWM controller uses a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. Charging current is programmable with a sense resistor and programming resistor to ±4% typica
