The LTC3773 is a high performance, 3-phase, triple output synchronous step-down switching regulator controller with output voltage power up/down tracking capability. The controller allows for sequential, coincident or ratiometric tracking.This 3-phase controller drives its output stages with 120? phase separation at frequencies of up to 700kHz per phase minimizing the RMS input current. Light load efficiency can be maximized by using selectable Burst Mode operation. The 0.6V precision reference supports output voltages from 0.6V to 5V.Fault protection features include output overvoltage, input undervoltage lockout plus current foldback under short-circuit or overload conditions.Applications Servers, Telecom, Industrial Power Supplies General Purpose Multiple Rail DC/DC FPGA and DSP Requirements

The LTC3530 is a wide VIN range, highly efficient, fixed frequency, buck-boost DC/DC converter that operates from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single lithium-ion, two-cell alkaline or NiMH applications where the output voltage is within the battery voltage range.The LTC3530 is pin compatible with the LTC3440 buckboost DC/DC converter but adds programmable automatic Burst Mode operation and extends the VIN/VOUT range to 1.8V. Switching frequencies up to 2MHz are programmed with an external resistor. Automatic Burst Mode operation allows the user to program the load current threshold for Burst Mode operation using a single resistor from the BURST pin to GND.Other features include 1?A shutdown, short circuit protection, programmable soft-start control, current limit and thermal shutdown. The LTC3530 is available in a thermally enhanced 10-lead (3mm ? 3mm) DFN or MSOP package.Applications MP3 Players Handheld Instruments Digital Cameras Smart Phones Portable GPS Units Miniature Hard Disk Drive Power

Demonstration circuit 943 is a complete power controller for a USB power device. It features the LTC6047 and provides a full-featured 1.25A linear lithium-ion CC/CV battery charger with timer termination and 4.2V charge voltage, a USB power manager, and a PowerPath manager for the battery. The USB input voltage range is 4.35V to 5.5V and the wall adapter input is 4.35V to 6V. It also features a programmable 1.5A input current limit that can be set at 500mA or 100mA for USB applications. The wall adapter input has overvoltage protection up to 13V. An external MOSFET disconnects the wall adapter when the voltage exceeds 6V.
