FEATURES - 2 Input Voltage Range: 3 V to 22 V - Output Voltage Range: 0.6 V to 2 V - 8-A or 10-A Integrated FET Converter (see Table 1) - Fewest External ponents - Soft-Start Time Programmable by External Capacitor - Switching Frequency: 400 k Hz and 800 k Hz - D-CAP2™ Architecture to Enable POSCAP and All MLCC Output Capacitor Usage - Integrated and Temperature pensated Low-Side On-Resistance Sensing for Accurate OCL Protection - Powergood Output OCL, OVP, UVP and UVLO Protections - Thermal Shutdown (non-latch) - Output Discharge Function - Integrated Boost MOSFET Switch - 28-Pin, 3.5-mm × 4.5-mm, RVE, QFN Package with 0.4-mm Pitch and 1-mm Height DESCRIPTION The TPS51363 is a high-voltage input, synchronous converter with integrated FET, based on D-CAP2™ control topology, which enables fast transient response and supports both POSCAP and all MLCC output capacitors. TI proprietary FET technology bined with TI leading-edge package technology provides the highest density solution for single-output power rail such as VCCIO and VDDQ for DDR notebook memory, or any point-of-load (POL) in wide application. The feature set includes switching frequency of 400 k Hz and 800 k Hz. Programmable soft-start time with an external capacitor. auto skip, pre-bias startup, integrated bootstrap switch, power good, enable and a full suite of fault protection schemes, including OCL, UVP, OVP, 5-V UVLO and thermal shutdown. It is packaged in 3.5 mm × 4.5 mm, 0.4-mm pitch, 28pin QFN (RVE), and specified from -10°C to 85°C. Table 1.
