DC1600A: Demo Board for the LTC6412 800MHz, 31dB Range Analog-Controlled VGA.

Demonstration Circuit 164 is a constant-frequency step-down (buck) regulator using the LTC1624 switching regulator controller. DC164 is ideal for a wide range of portable, industrial, computer and communications applications. It provides up to 3A of output current at a user-selectable (via a jumper) output voltage of 2.5V, 3.3V or 5V. The input voltage can range from 4.8V to 28V (limited by the external MOSFET).

DC1627A-B: Demo Board for the LTC4226 Wide Operating Range Dual Hot Swap Controller.

Demonstration circuit DC2380A features the LTC7851, a high performance 4-phase step-down, voltage mode controller. The DC2380A-C operates with a 7V to 14V input supply voltage and provides a single 1.2V @ 120A output. The LTC7851’s integrated current share circuit provides highly accurate current sharing. Since the LTC7851 does not include MOSFET drivers, its PWM outputs drive external DrMOS devices.

Demonstration circuit 1286A is DC/DC boost converter featuring the LTC3862EGN/-1 constant frequency current mode boost controllers. The DC1286A-A (LTC3862) operates over 5V to 36V input and provides 2A-5A of output current at 48V output. The DC1286A-B (LTC3862-1, higher VIN min and higher gate drive) operates over 8V to 36V input and provides 3A-5A of output current at 48V output. The 200kHz constant frequency operation results in small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.

DC665A: Demo Board for the LT4220 Dual Supply Hot Swap Controller.

Demonstration circuit DC2380A features the LTC7851, a high performance 4-phase step-down, voltage mode controller. The DC2380A-B operates with a 7V to 14V input supply voltage and provides the follow two high current outputs: 1.8V @ 60A and 1.2V @ 60A. The LTC7851’s integrated current share circuit provides highly accurate current sharing. Since the LTC7851 does not include MOSFET drivers, its PWM outputs drive external DrMOS devices.

Demonstration circuit 2348A is a high power high efficiency bi-directional synchronous buck or boost converter featuring the LTC3871 and is available in two versions. The DC2348A-A operates with two each LTC3871 devices with four phases and the DC2348A-B utilizes one LTC3871 device with two phases.

DC1080A: Demo Board for the LTC4268-1 High Power PD with Synchronous No Opto Flyback Controller.

Demonstration circuit 1317A-H is isolated input to high current output 1/8th Brick footprint converter featuring the LT1952 switching controller with Active Reset circuit. The Active Reset circuit can improve the efficiency in wide input voltage applications. Also, the Active Reset allows the implementation of self-driven synchronous secondary rectifiers in some applications. The DC1317A-H converts isolated 9V to 36V input to 48V output and provides 1.5A of output current.
