The LTC3897 is a synchronous boost DC/DC controller with surge stopper and ideal diode controller.The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor?requirements, allowing the use of smaller inductors than the single-phase equivalent. Synchronous rectification reduces power loss and eases thermal requirements.The surge stopper controls the gate of an external N-channel MOSFET to protect against high voltage input transients and provides in-rush current control, overcurrent protection and output disconnect for the boost converter. The integrated ideal diode controller drives another N-channel MOSFET to replace a Schottky diode for reverse input protection and voltage holdup or peak detection. It controls the forward voltage drop across the MOSFET and minimizes reverse current flow.The LTC3897 is available in thermally-enhanced 38-pin leadless QFN or 38-lead TSSOP packages.Applications Industrial Automotive Military/Avionics

The LTC3649 is a high efficiency 60V, 4A synchronous monolithic step-down regulator. The regulator features a single resistor programmable output voltage, internal compensation and high efficiencies over a wide VOUT range.The step-down regulator operates from an input voltage range of 3.1V to 60V and provides an adjustable rail-to-rail output range from (VIN ? 0.5V) to ground while delivering up to 4A of output current. The switching frequency is also adjusted with an external resistor. A user-selectable mode input is provided to allow the user to trade off ripple noise for efficiency at light loads; Burst Mode operation provides the highest efficiency at light loads, while forced continuous mode provides low output ripple. The MODE/SYNC pin can also be used to allow the user to synchronize the switching frequency to an external clock.The LTC3649 operates with a peak current mode architecture that allows for fast transient response with inherent cycle-to-cycle current limit protection. It also features programmable output current limit, current monitoring and input voltage regulation.Applications Industrial Applications Automotive Applications

The LTC4079 is a low quiescent current, high voltage linear charger for most battery chemistry types including Li-Ion/Polymer, LiFePO4, Lead-Acid or NiMH battery stacks up to 60V. The maximum charge current is adjustable from 10mA to 250mA with an external resistor. The battery charge voltage is set using an external resistor divider.With an integrated power device, current sensing and reverse current protection, a complete charging solution using the LTC4079 requires very few external components. Thermal regulation ensures maximum charge current up to the specified limit without the risk of overheating. Charging can be terminated by either C/10 or adjustable timer.Input voltage regulation reduces charge current when the input voltage falls to an adjustable level or the battery voltage, making it well suited for energy harvesting applications. Other features include temperature qualified charging, bad battery detection, automatic recharge with sampled feedback in standby for negligible battery drain, and an open-drain CHRG status output. The device is offered in a compact, thermally enhanced 10-lead (3mm ? 3mm) DFN package.APPLICATIONS Embedded Automotive and Industrial Backup Battery Charging from Another Battery Energy Harvesting Charger Thin Film Battery Products
