Demonstration circuit DC1194A features the LTM8020, a 200mA DC/DC step-down μModule® regulator. The board is preset to deliver a 3.3V output at up to 200mA load current from an input voltage from 4.5V up to 36V. The output voltage may be modified by simply changing one resistor.

The LTM8023 is a complete 2A, DC/DC step-down power supply. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.6V to 36V, the LTM8023 supports an output voltage range of 0.8V to 10V, and a switching frequency range of 200kHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.The LTM8023 is packaged in a thermally enhanced, compact and low profile over-molded land grid array (LGA) and ball grid array (BGA) packages suitable for automated assembly by standard surface mount equipment. The LTM8023 is available with SnPb (BGA) or RoHS compliant terminal finish.Applications Automotive Battery Regulation Power for Portable Products Distributed Supply Regulation Industrial Supplies Wall Transformer Regulation

DC1203A: Demo Board for LTC4357 Positive High Voltage Ideal Diode Controller.

Demonstration circuit 1208A features the LTC4151 high side power monitor that accepts input voltages from 7V to 80V. In default operation mode, the onboard 12-bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I2C interface when polled by a host. The monitors can also perform on-demand measurement in a snapshot mode. The LTC4151 features a dedicated shutdown pin to reduce power consumption.

Demonstration circuit 1219A-A, A-B, A-C and A-D are micropower low noise boost converters with output disconnect featuring the four different LT3495 versions: LT3495 (0.65A switch current, switching frequency above audible range), LT3495B (0.65A switch current), LT3495-1 (0.35 switch current, switching frequency above audible range) and LT3495B-1 (0.35A switch current). All versions convert a 3V-6V source to 15V. The A-A and A-B versions supply 75mA at 3VIN, while the A-C and A-D supply 36mA.  All versions feature a low noise control scheme, integrated output disconnect function, dimming control and a single output sense resistor.

Demonstration circuit 1222 is a monolithic stepdown DC/DC switching regulator featuring the LT3682. The demo board is designed for 5V at 1A (VIN > 12V) from a 6.9V to 36V input, with transients up to 60V.

Demonstration circuit 1231A is a Dual Output, Dual Phase 5A Synchronous Buck Converter featuring the LTC3850EGN. The entire circuit, including the bulk output capacitors, fit within a 1.04” × 0.94” area on all layers. The package style for the LTC3850EGN is a 28-lead narrow plastic SSOP. The main features of the board include rail tracking, an internal 5V linear regulator for bias, RUN pins for each output and a PGOOD signal and a Mode selector that allow the converter to run in CCM, pulse skip or Burst Mode operation. Synchronization to an external clock is also possible through some minor component changes. Two versions of the board are available. DC-1231A-A has an on-board sense resistor for current feedback, while the DC1231A-B is configured with a DCR sense circuit that allows the converter to use the inductor’s DCR as the sense element instead of the on-board sense resistors to save cost and board space and improves efficiency.

DC1232A: Demo Board for the LT3437 - High Voltage 500mA, 200kHz Step-Down Switching Regulator with 100µA Quiescent Current

The LTC3527/LTC3527-1 are dual high efficiency, step-up DC/DC converters in a space saving 16-lead 3mm ? 3mm QFN package. Battery life is maximized with a 700mV startup voltage and operation down to 500mV once started. The SHDN and PGOOD pins enable the converters to be sequenced or started together. The LTC3527/LTC3527-1 limit inrush current during startup. Selectable 1.2MHz or 2.2MHz operation provides a choice between the highest efficiency or smallest solution footprint. The current mode PWM design is internally compensated reducing external parts count. Burst Mode operation or fixed frequency operation is selectable via the MODE pin. Anti-ring circuitry reduces EMI in discontinuous mode. This device also features thermal shutdown. True output disconnect allows the output to be completely open in shutdown. The LTC3527-1 actively discharges VOUT1 or VOUT2 when its respective SHDN goes low. Quiescent current in shutdown is less than 2?A.Applications MP3/Personal Media Players Noise Canceling/Bluetooth Headsets Wireless Mice Portable Medical Instruments
