Analog Devices LTC4100EG | Demoboard DC512B
LTC4100EG | 3-/4-Cell Li-Ion Smart Battery Charger, DCIN = 15V-20V, Up to 4A Charge Current, (req. DC1223)
Overview
| Topology | Boost Converter |
| Input voltage | 15-20 V |
| Output 1 | 32.75 V / 4.09 A |
| Output 2 | 16.87 V / 3.07 A |
| IC revision | 1 |
Description
Demonstration circuit DC512B is a single battery switching step-down charge controller featuring the LTC4100. The recommended input power is 15 to 20V at 3.5A. A two-position jumper allows choice of protected outputvoltage range suitable for 3- and 4-Cell Li-ion batteries. Removal of the jumper allows full output voltage range. The maximum charge current is 4A.
The demo board is initially configured for 12.6V at 3A for popular 3-cell Li-ion battery packs. LTC4100 will automatically charge a Smart Battery to termination as soon as input power is applied with a battery connectedprior to power up. A VOUT pin automatically provides power to the system load from the wall adapter or battery.Status LEDs are provided for CHG, ACP,SMBALERT and SMBus activity.
The optional DC1223A-B SMBUS to USB adapter and associated software to control, monitor, and data log the system for demonstration purposes only. This software is not required to charge a battery with the DC512B.Contact your LT representative for ordering a DC1223A-B.
