Demonstration circuit 1852A is a combined step-up and step-down DC/DC converter, using the LTC3536 monolithic synchronous buck-boost regulator in the MSOP package. The DC1852A has wide input voltage range of 1.8V to 5.5V and is capable of delivering up to 1A of output current. The output voltage of the DC1852A can be set as low as 1.8V and can go as high as 5.5V. DC1852A supports two operation modes: fixed-frequency pulse-width modulation (PWM) and Burst Mode® operation.

The LTM4649 is a complete 10A high efficiency switching mode step-down DC/DC ?Module? regulator in a 9mm ? 15mm ? 4.92 BGA package. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over an input voltage range of 4.5V to 16V, the LTM4649 supports an output voltage range of 0.6V to 3.3V, set by a single external resistor. This high efficiency design delivers 10A continuous current. Only bulk input and output capacitors are needed.High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, programmable multiphase operation, and output voltage tracking for supply rail sequencing.Fault protection features include output overvoltage and overcurrent protection. The LTM4649 is offered in a small 9mm ? 15mm ? 4.92mm BGA package available with SnPb or RoHS compliant terminal finish.Applications Telecom, Networking and Industrial Equipment Point of Load Regulation

The LT3029 is a dual, micropower, low noise, low dropout linear regulator. The device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. Each output supplies up to 500mA of output current with a typical dropout voltage of 300mV. Quiescent current is well controlled in dropout. With an external 10nF bypass capacitor, output noise is only 20?VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 55?A quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 1?A. Shutdown control is independent for each channel, allowing for flexible power management.The LT3029 optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3?F. The regulator does not require the addition of ESR, as is common with other regulators.Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. The LT3029 is offered in the thermally enhanced 16-lead MSOP and 16-lead, low profile (4mm ? 3mm ? 0.75mm) DFN packages.Applications General Purpose Linear Regulator Battery-Powered Systems Microprocessor Core/Logic Supplies Post Regulator for Switching Supplies Tracking/Sequencing Power Supplies

Demonstration circuit DC2448A-D features a PolyPhase® design using the LTM4636-1EY, a 40A high efficiency, switch mode step-down power µModule® regulator with overvoltage and overtemperature protection features. The input voltage range is from 9V to 15V. The output voltage range is 0.6V to 3.3V. The DC2448A-D can deliver a nominal 160A output current. DC2448A-D has on-boardhot swap circuit that can disconnect input supply and protect the LTM4636-1 and the load under overvoltage and overtemperature conditions. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4636-1 to synchronize to an external clock signal. DC2448A-D has the option of choosing both internal and external compensation circuits for LTM4636-1. The LTM4636-1 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2448A-D.
