The LTC3816 is a single-phase synchronous step-down DC/DC switching regulator controller that complies with Intel Mobile Voltage Positioning (IMVP)-6/6+/6.5 specifications. It uses a constant-frequency voltage mode architecture with a leading edge modulation topology, allowing extremely low output voltages and very fast load transient response. The LTC3816 satisfies all of the IMVP-6, IMVP-6+ and IMVP-6.5 requirements, including 7-bit VID code, start-up to a preset boot voltage, differential remote output voltage sensing with programmable active voltage positioning (AVP), IMON output current reporting, power optimization during sleep state and fast or slow slew rate sleep state exit. It is suitable for a wide range of input voltages from 4.5V to 36V and output voltages up to 1.5V. The LTC3816 is available in 38-pin thermally enhanced eTSSOP and 5mm × 7mm QFN packages.
