The PCNT pin enables • Minimum External Parts Count operation in dual or single-phase mode to optimize • 8-Bit DAC Supports Wide Range of efficiency depending on the load requirements. Applications Advanced control features such as D-CAP+™ architecture and OSR provides fast transient • Optimized Efficiency at Light and Heavy Loads response with low output capacitance. The DAC • Patented Output Overshoot Reduction (OSR) supports VID-on-the-fly to optimize the output voltage Reduces Output Capacitance to the operating state of the system to reduce • Accurate, Adjustable Voltage Positioning quiescent power. The auto-skip feature of the TPS53624 optimizes light-load efficiency in single • Selectable 200, 300, 400 and 500 kHz phase operation. System management features Frequency include adjustable thermal monitor input and output • Pat. Pending AutoBalance Phase Balancing (THRM, THAL), output current monitoring (IMON), • Selectable 8-Level Current Limit and complimentary power good signals (PG and PGD). Adjustable control of the output voltage slew • 3-V to 28-V Conversion Voltage Range rate and voltage positioning are provided. In addition, • Fast MOSFET Driver with Integrated Boost the TPS53624 includes two high-current FET gate Diode drivers to drive high and low side N-channel FETs with exceptionally high speed and low switching loss. • Integrated Overvoltage Protection (OVP) All logic input and output pins have flexible LV input • Small 6 × 6, 40-Pin QFN PowerPAD™ Package and output thresholds that enable interface with logic voltages from 1 V to 3.6 V. APPLICATIONS The TPS53624 is packaged in a space saving, • High-Current, Low-Voltage ASIC or thermally enhanced, RoHS compliant 40-pin QFN Microprocessor Core Regulator and is rated to operate from –10°C to 105°C.
