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 output voltage 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 connected prior 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.

Demonstration circuit 516A-A is a low output voltage, synchronous boost converter featuring the LTC3423. The LTC3423 is ideal for applications that require an output voltage between 1.5V to 2.6V from a single alkaline or NiCd/NiMH cell. A bias voltage (VDD) of 2.7V to 5.5V is required to power the internal circuitry. The input voltage (VIN) range is 1V to 1.6V, but once up and running, the device can operate with an input voltage as low as 0.5V. The output voltage is set at 1.8V. For a 1V minimum battery voltage, the LTC3423 can provide 350mA.

The LTC4052 is a complete standalone pulse charger with integrated MOSFET for 1-cell lithium-ion batteries.An external sense resistor provides overcurrent limiting as a safety precaution against a user connecting a wall adapter with the incorrect or no current limit. The internal MOSFET prevents reverse battery current from flowing if the input voltage is shorted to ground, eliminating the need for a blocking diode.As the battery accepts charge and approaches the programmed float voltage, the internal MOSFET begins switching off and on with the duty cycle gradually decreasing as the battery approaches a fully charged condition. A programmable timer terminates the charge cycle. The near end-of-charge C/10 condition is indicated at the CHRG pin when the average charge current falls to one tenth of the wall adapter current. Removing the input voltage puts the LTC4052 into a sleep mode, dropping the battery current drain to less than 1?A.The LTC4052 is available in a tiny 8-pin thermally enhanced MSOP package.Applications Handheld Computers Cellular Telephones Cradle Chargers

Demonstration circuit 533 is an 800kHz adjustable output boost regulator featuring the LT3436. This current-mode control monolithic (switch included) converter has a wide operating supply voltage of 3V to 25V and a minimum peak switch current rating of 3A, though the demo board has a reduced input voltage range of 3.2V to 12V. It provides 12V at 550mA from a 3.3V input and 12V at 900mA from a 5V input.

Demonstration circuit 534 is a fast transient response, very low dropout linear regulator featuring the 4A output current LT3150 linear regulator controller. The DC534 has an input voltage range of 1.1V to 10V and generates a jumper-selectable output voltage of 1.2V, 1.5V or 1.8V. With the LT3150 driving external N-channel MOSFETs as source followers, the DC534 can produce very fast transient response. The proper selection of the Rds(on) of the MOSFETs allows dropout voltages below 300 mV. These capabilities, plus its ability to maintain stable operation with ceramic output capacitors, make the DC534 voltage regulator ideally suited for low VIN-to-VOUT applications, such as microprocessor/microcontroller/FPGA power supplies.
