Demonstration circuit DC1259A is a single-battery battery- backup controller featuring the LTC4110. The LTC4110 controller provides all the features and functions to offer a complete standalone battery-backup system. The LTC4110 is a multi-chemistry flyback battery charger and discharger that is scalable with other LTC4110s to allow a larger battery array for increased capacity and/or redundancy. The demo board requires a 12V input voltage and is initially configured to charge a 3 Li-Ion Smart Battery at 1A; the charge voltage is 12.6V. However, the Demo board can be easily configured for a standard battery as well. A SMBus interface is offered to allow host communications in control and status and/or support Smart Batteries. However, no host is required to use the LTC4110.

Demonstration circuit 1261A features the LTM8022 step-down μModule® regulator delivering a 3.3V/1A output from a 4.5V to 36V input supply. As a step-down converter, the LTM8022 requires a minimum amount of headroom to keep the output in regulation. Current sharing with another LTM8022 is enabled by tying the VIN, VOUT and SHARE pins together to support higher output loads.

The LTC4219 is an integrated solution for Hot Swap applications that allows a board to be safely inserted and removed from a live backplane. The part integrates a Hot Swap controller, power MOSFET and current sense resistor in a single package for small form factor applications. The LTC4219 provides separate inrush current control and a 10% accurate 5.6A current limit with foldback current limiting. The current limit threshold can be adjusted dynamically using an external pin. Additional features include a current monitor output that amplifies the sense resistor voltage for ground referenced current sensing and a MOSFET temperature monitor output. Thermal limit and power good monitoring are also provided. The power good detection level and foldback current limit profile are internally preset for 5V (LTC4219-5) and 12V (LTC4219-12) applications.Applications RAID Systems Server I/O Cards Industrial

Demonstration Circuit 1598A is a fixed frequency synchronous buck-boost converter with an extended input and output range. The unique 4-switch, single inductor architecture provides low noise and seamless operation from input voltages above, below, or equal to the output voltage. The LTC3112 features selectable PWM or Burst Mode operation, and an easily synchronizable oscillator. An output current monitor allows the load current to be controlled or monitored. The LTC3112 operates with a 2.7V to 15V input voltage range and a VOUT range from 2.5V to 14V. The demonstration board has been designed to operate with VIN from 2.7V to 15V and an output current up to 2.5A. For VIN < 5V, IOUT capability is reduced. VOUT is set to 5.0V.

Demonstration circuit 1614 features the LTC4012CUF, a multi-chemistry single battery charger controller with PowerPath™ control. The input supply voltage is 13.5V to 20V and is initially configured for a current limit of 10A. The charger float voltage is programmed by jumpers to support 1- to 4- series cells of both Li-Ion/Polymer and Li-iron phosphate (LiFePO4) at 4.2V/cell and 3.6V/cell, for a total of eight settings. The demo board is initially configured for constant-voltage charging of a 12.6V Li-Ion/ Polymer battery and constant-current charging at 8A, though current derating may be necessary due to certain operating conditions.
