Demonstration Circuit DC1658A is a 20V High Efficiency Nanopower Step-Down Regulator featuring the LTC3388-1/ LTC3388-3. The LTC3388 is an ultralow quiescent current power supply designed to regulate the output voltage by means of a nanopower high efficiency synchronous buck regulator. The input current is only 720nA typical at no load while maintaining output voltage regulation, capable of supplying 50mA of load current. The LTC3388-1/ LTC3388-3 also incorporates an accurate undervoltage lockout feature to disable the converter and maintain a low quiescent current state when the input voltage falls below 2.3V. In regulation, the LTC3388-1/LTC3388-3 enter a sleep state in which both input and output quiescent currents are minimal. The buck converter turns on and off as needed to maintain regulation. An additional standby mode disables the buck switching while the  output is in regulation for short duration loads requiring low ripple.

The LTC2654 is a family of quad 16-/12-bit rail-to-rail DACs with integrated 10ppm/?C maximum reference . The DACs have built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2654-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. The LTC2654-H has a full-scale output of 4.096V with the integrated reference and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the full-scale output to 2 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 LTC2654 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. If PORSEL is tied to VCC, the DACs reset to mid-scale.Applications Mobile Communications Process Control and Industrial Automation Instrumentation Automatic Test Equipment Automotive
