The LT3663 is a current mode step-down switching regulator with programmable output current limit. The current limit accurately controls the system power dissipation and reduces the size of the power path components. The wide operating input voltage range of 7.5V to 36V (60V transient) suits the LT3663 to a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, and automotive power. The LT3663 includes a low current shutdown mode, input overvoltage and undervoltage lockout, and thermal shutdown. Internal compensation and boost diode minimize the number of external exponents. 3.3V and 5V fixed output voltage versions are available. The LT3663 is available in 8-lead DFN and MSOP packages with exposed pads for low thermal resistance.Applications Distributed Supply Regulation Automotive Battery Regulation Industrial Supplies Wall Transformer Regulation

The LTC3838 is a dual, PolyPhase? synchronous step-down DC/DC switching regulator controller. Two independent channels drive all N-channel power MOSFETs. The controlled on-time, valley current mode control architecture allows for fast transient response and constant frequency switching in steady-state operation, independent of VIN, VOUT and load current. Its load-release transient detection feature significantly reduces overshoot at low output voltages.Differential output voltage sensing, along with a precision internal reference, offers an accurate ?0.67% output regulation on Channel 1, even if the remote output ground deviates from local ground by ?500mV. The second channel can either provide an independent ?1% output, or together with the first channel of this controller, serve as one of the PolyPhase channels for a single-output voltage.The switching frequency can be programmed from 200kHz to 2MHz with an external resistor, and can be synchronized to an external clock. Very low tON and tOFF times allow for near 0% and near 100% duty cycles, respectively. Voltage tracking soft start-up and multiple safety features are provided.See below for a comparison of LTC3838, LTC3838-1 and LTC3838-2.
