Each DAC can also operate with an external reference, which sets the DAC full-scale output to two times the external reference voltage.These DACs communicate via a SPI/MICROWIRE? compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2656 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale.

The LT1170/LT1171/LT1172 are monolithic high power switching regulators. They can be operated in all standard switching configurations including buck, boost, flyback, forward, inverting and ?Cuk.? A high current, high efficiency switch is included on the die along with all oscillator, control and protection circuitry. Integration of all functions allows the LT1170/LT1171/LT1172 to be built in a standard 5-pin TO-3 or TO-220 power package as well as the 8-pin packages (LT1172). This makes them extremely easy to use and provides ?bust proof? operation similar to that obtained with 3-pin linear regulators. The LT1170/LT1171/LT1172 operate with supply voltages from 3V to 60V, and draw only 6mA quiescent current. They can deliver load power up to 100W with no external power devices. By utilizing current-mode switching techniques, they provide excellent AC and DC load and line regulation. The LT1170/LT1171/LT1172 have many unique features not found even on the vastly more difficult to use low power control chips presently available. They use adaptive antisat switch drive to allow very wide ranging load currents with no loss in efficiency. An externally activated shutdown mode reduces total supply current to 50?A typically for standby operation.Applications Logic Supply 5V at 10A 5V Logic to ?15V Op Amp Supply Battery Upconverter Power Inverter (+ to ?) or (? to +) Fully Floating Multiple OutputsUser Note:This data sheet is only intended to provide specifications, graphs, and a general functional description of the LT1170/LT1171/LT1172.

The LTC3588-2 integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric, solar, or magnetic transducers.An ultralow quiescent current undervoltage lockout (UVLO) mode with a 16V rising threshold enables efficient energy extraction from sources with high open circuit voltages. This energy is transferred from the input capacitor to the output via a high efficiency synchronous buck regulator. The 16V UVLO threshold also allows for input to output current multiplication through the buck regulator. The buck features a sleep state that minimizes both input and output quiescent currents while in regulation.Four output voltages of 3.45V, 4.1V, 4.5V and 5.0V are pin selectable with up to 100mA of continuous output current, and suit Li-Ion and LiFePO4 batteries as well as supercapacitors.

The LTC3620 is a high efficiency, synchronous buck regulator, suitable for very low power, very small footprint applications powered by a single Li-Ion battery.The internal synchronous switches increase efficiency and eliminate the need for external Schottky diodes. Low output voltages are easily supported by the 0.6V feedback reference voltage. The LTC3620-1 option is internally programmed to provide a 1.1V output.The LTC3620 uses a unique variable frequency architecture to minimize power loss and achieve high efficiency. The switching frequency is proportional to the load current, and an internal frequency clamp forces a minimum switching frequency at light loads to minimize noise in the audio range. The user can program the frequency of this clamp by applying an external clock to the FMIN/MODE pin.The battery status output, LOBATB, indicates when the input voltage drops below 3V. To help prevent damage to the battery, an undervoltage lockout (UVLO) circuit shuts down the part if the input voltage falls below 2.8V.The LTC3620 is available in a low profile, 2mm ? 2mm 8-lead DFN package.Applications Hearing Aids Wireless Headsets Li-Ion Cell Applications Button Cell Replacement
