The LTC3726 is a secondary-side controller for synchronous forward converters. When used in conjunction with the LTC3705/LTC3725 gate driver and primary-side controllers, the part creates a complete isolated power supply that combines the simplicity of OPTI-LOOP? compensation with the speed of secondary-side control.The LTC3726 has been designed to simplify the design of highly efficient, secondary-side forward converters. Working in concert with the LTC3705 or LTC 3725, the LTC3726 forms a robust, self-starting converter that eliminates the need for the separate bias regulator that is commonly used in secondary-side control applications. In addition, a proprietary scheme is used to multiplex gate drive signals and DC bias power across the isolation barrier through a single, tiny pulse transformer.The LTC3726 is available in a 16-lead SSOP package.Applications Isolated 48V Telecommunication Systems Internet Servers and Routers Distributed Power Step-Down Converters Automotive and Heavy Equipment

The RS-485 transceivers are available in a number of spacesaving packages, including the 10-lead, 3 mm ? 3 mm lead framechip-scale package (LFCSP), the 8-lead or 10-lead, 3 mm ? 3 mmmini small outline package (MSOP), and the 8-lead or 14-lead,narrow body standard small outline packages (SOIC_N).Models with operating temperature ranges of ?40?C to +125?Cand ?40?C to +85?C are available. Excessive power dissipation caused by bus contention or byoutput shorting is prevented by a thermal shutdown circuit. If asignificant temperature increase is detected in the internal drivercircuitry during fault conditions, this feature forces the driveroutput into a high impedance state.

Demonstration circuit DC2343A is a complete system level solution for a nanopower buck-boost DC/DC with integrated coulomb counter. The DC2343A contains a PIC16F1459 embedded processor for communication to the PC over USB and the LTC3335 via its I2C port. The GUI is capable of reading and writing all the control registers on the LTC3335 as well as displaying and resetting all its alarm registers. The firmware and software for the embedded system and the GUI are available at the LTC3335 solutions page. The DC2343A uses two analog-to-digital converter channels to sample the battery and output voltages. The voltage samples improve the functionality of the GUI, and allow optimal software correction to the measured coulombs. By adding the software correction the first order known errors are compensated for over the operating range and the resultant coulomb count is accurate to within 3%.

The ADuM4146 is a single-channel gate driver specifically optimized for driving silicon carbide (SiC), metal-oxide semiconductor field effect transistors (MOSFETs). Analog Devices, Inc., iCoupler? technology provides isolation between the input signal and the output gate drive.The ADuM4146 includes a Miller clamp to provide robust SiC turn off with a single-rail supply when the gate voltage drops to less than 2 V. Operation with unipolar or bipolar secondary supplies is possible with or without the Miller clamp operation.The Analog Devices chip scale transformers also provide isolated communication of control information between the high voltage and low voltage domains of the chip. Information on the status of the chip can be read back from dedicated outputs. Control of resetting the device after a fault on the secondary side is performed on the primary side of the device.Integrated onto the ADuM4146 is a desaturation detection circuit that provides protection against high voltage short-circuit SiC operation. The desaturation protection contains noise reducing features, such as a 300 ns masking time after a switching event to mask voltage spikes due to initial turn on (see Figure 17 in the data sheet). An optional internal 500 ?A current source allows low device count, and the internal blanking switch allows the addition of an external current source if more noise immunity is needed.The secondary undervoltage lockout (UVLO) is set to 14.5 V (typical) for Grade A and is set to 11.5 V (typical) for Grade B and Grade C with common SiC and insulated gate bipolar transistor (IGBT) levels taken into consideration.

Demonstration circuit 2898A is a dual DC/DC converter with a 13V to 40V input voltage range, two 12V outputs at 4A each featuring the LTM4655. The LTM4655 is a EN55022B compliant 40V, dual 4A or single 8A step-down or 50W inverting DC/DC μModule® regulator. The switching frequencies of both channels are set at 1.2MHz on DC2898A. If the output voltage collapses sufficiently due to an overload or short-circuit condition, the internal oscillator will foldback to one-fifth of the LTM4655’s programmed switching frequency, protecting the power switch from damage. Key features of this board include: SSFM Jumper for Spread Spectrum Options CLKIN Inputs for External Sync PGOOD Signals for Each Output The two channels can be paralleled for higher output current. See the data sheet for more information on setting up the board for paralleling the two outputs. The LTM4655 data sheet gives a complete description of the device, its operation and application information. The data sheet must be read in conjunction with the demo manual prior to working on or modifying DC2898A.
