It operates from an input voltageranging from 4.5V to 36V, has powerful onboard N-channel MOSFET gate drivers and cancontrol output currents up to 25A.
Its leading edge modulation architecture enables a very lowoutput voltage to be regulated from a high input voltage and still operate at high frequency(phase-lockable up to 550kHz). A unity-gain differential amplifier provides remote voltage-sensing at the CPU, eliminating errors due to parasitic IR drops across PCB metal traces.Current sensing can be implemented with either a temperature-compensated lossless
inductor DCR network, or with a discrete sense resistor. If DCR sensing is used, an NTCthermistor network will compensate for the gain and time constant variations caused by theinductor DCR temperature coefficient.The LTC3816 can operate in pulse-skipping or forced continuous mode. Pulse skippingprovides the highest light load efficiency, while forced continuous operation has faster transientresponse at light load. AVP minimizes the peak-to-peak output voltage transient during a stepload.
The LTC3816 is available in thermally enhanced 38-lead SSOP or 38-lead 5mm x7mm QFN packages and operates over a -40°C to 125°C operating junction temperature range.1000-piece price starts at $3.25 each. Both versions are available from stock.
