Demonstration circuit 833 is an ultralow dropout voltage supply using the 1.5A output current LTC3026 linear regulator in a small 3mm × 3mm 10-Pin DFN package. The DC833 has an input voltage range from 1.14V to 3.5V when the internal boost converter is enabled, and a maximum input voltage of 5.5V when an external source is supplied. The output voltage jumper-selectable and can be set to 0.8V, 1.2V, 1.5V, 1.5V, 1.8V or a user-defined value between 0.4V and 2.6V. The 0.4V reference of the LTC3026 allows the DC833 to supply power to very low voltage applications. The DC833 is also an excellent choice for post regulation of step-down switching regulators, creating a high efficiency low-noise supply. The DC833 comes assembled with small ceramic capacitors, showing the LTC3026's ability to maintain stability with ceramic output capacitors.

The LT3477 is a current mode, 3A DC/DC step-up converter with dual rail-to-rail current sense amplifiers and an internal 3A, 42V switch. It combines a traditional voltage feedback loop and two unique current feedback loops to operate as a constant-current, constant-voltage source. Both current sense voltages are set at 100mV and can be adjusted independently using the IADJ1 and IADJ2 pins. Efficiency of up to 93% can be achieved in typical applications. The LT3477 features a programmable soft-start function to limit inductor current during start-up. Both inputs of the error amplifier are available externally allowing positive and negative output voltages (boost, inverting, SEPIC, Flyback). The switching frequency is programmable from 200kHz to 3.5MHz through an external resistor.Available in thermally enhanced 20-pin (4mm ? 4mm) QFN and 20-pin TSSOP packages, the LT3477 provides a complete solution for both constant-voltage and constantcurrent applications.Applications High Power LED Driver DSL Modems Distributed Power Input/Output Current Limited Boost, SEPIC, Inverting, Flyback Converters Constant-Voltage, Constant-Current Source

The LT3479 is a current mode, fixed frequency step-up DC/DC converter with an internal 3A, 42V switch. Efficiencies of up to 89% can be achieved in typical applications. It features a programmable soft-start function to limit inductor current during start-up and inrush current protection to protect the LT3479 during shorts and line transients. Both inputs of the error amplifier are available to the user allowing positive and negative output voltages. Through an external resistor, the user can program the switching frequency from 200kHz to 3.5MHz. The low profile (0.75mm) 14-pin, 4mm ? 3mm DFN package provides excellent thermal performance in a small footprint. The LT3479 is also available in a thermally enhanced 16-pin TSSOP package.Applications High Power LED Driver DSL Modems Distributed Power

Demonstration circuit 862 is a micropower regulated charge pump DC/DC converter featuring the 60mA output LTC3221 in a 2mmx2mm DFN package. It comes in three assembly versions, DC862A-A, DC862A-B and DC862A-C, featuring the LTC3221EDC-3.3 (fixed 3.3V output), the LTC3221EDC-5 (fixed 5V output) , and LTC3221EDC (adjustable output set to 3V), respectively. The demo board input voltage range depends on the IC used; for the 3.3V output DC862A-A, the input voltage range is 1.8V to 4.4V. The LTC3221's low 8µA no-load quiescent current is even lower than the self-discharging current of many batteries. By employing a constant current to charge the output, the output ripple is low even at high input and light load, and is fairly constant over the full input voltage range.
