DC1532A-D: Demo Board for the LTC2265-14 14-Bit, 65Msps Low Power Dual ADCs.

The LTM8045 is a ?Module? (power module) DC/DC converter that can be configured as a SEPIC or inverting converter by simply grounding the appropriate output rail. In a SEPIC configuration the regulated output voltage can be above, below or equal to the input voltage. The LTM8045 includes power devices, inductors, control circuitry and passive components. All that is needed to complete the design are input and output capacitors, and small resistors to set the output voltage and switching frequency. Other components may be used to control the soft-start and undervoltage lockout.The LTM8045 is packaged in a compact (6.25mm ? 11.25mm) overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8045 is available with SnPb (BGA) or RoHS compliant terminal finish.Applications Battery Powered Regulator Local Negative Voltage Regulator Low Noise Amplifier Power

Demonstration circuit DC1555C is intended to demonstrate the performance of the LTC4365 and LTC4365-1 Undervoltage, Overvoltage and Reverse Supply Protection Controllers. The LTC4365/LTC4365-1 protect circuits from input voltages that may be too high, too low or negative. It operates by controlling the gates of two back-to-back connected MOSFETs to keep the output in a safe range. The OV and UV protection levels are adjusted by resistive dividers at the OV and UV pins. Asserting the SHDN pin disables the MOSFETs and places the controller in a low-current shutdown state. The FAULT pin is asserted when the Controller is in shutdown mode or when the input voltage is outside of the UV or OV level.

DC1561B: Demo Board for the LTC4278 IEEE 802.3at PD with Synchronous No-Opto Flyback Controller and 12V Auxiliary Support.

The LTC3615/LTC3615-1 are dual 3A synchronous stepdown regulators using a current mode, constant-frequency architecture. The DC supply current is only 130?A (Burst Mode operation at no-load) while maintaining the output voltages, dropping to zero current in shutdown. The 2.25V to 5.5V input supply range makes the parts ideally suited for single Li-Ion applications. 100% duty cycle capability provides low dropout operation, which extends operating time in battery-operated systems.The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. 0?, 90?, or 180? (LTC3615) or 140?/180? (LTC3615-1) of phase shift between the two channels can be selected to minimize input current ripple and output voltage ripple in a dual 3A or single 6A output configuration. Programmable slew rate limiting reduces EMI, and external synchronization can be applied up to 4MHz.The internal synchronous switches increase efficiency and eliminate the need for external catch diodes, saving external components and board space.The LTC3615/LTC3615-1 are offered in leadless 24-pin 4mm ? 4mm QFN and thermally enhanced 24-pin eTSSOP packages.Applications Point-of-Load Supplies Distributed Power Supplies Portable Computer Systems DDR Memory Termination Handheld Devices
