Description
The TPS54824 is a full featured 17-V, 8-A synchronous step-down converter in a 3.5 mm x 3.5 mm HotRod™ QFN package. The device is optimized for small solution size through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through peak current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor footprint. The peak current mode control simplifies the loop compensation and provides fast transient response. Cycle-by-cycle peak current limiting on the high-side and low-side sourcing current limit protects the device in overload situations. Hiccup limits MOSFET power dissipation if a short circuit or over loading fault persists. A power good supervisor circuit monitors the regulator output. The PGOOD pin is an open drain output and goes high impedance when the output voltage is in regulation. An internal deglitch time prevents the PGOOD pin from pulling low unless a fault has occurred. A dedicated EN pin can be used to control the regulator on/off and adjust the input under voltage lockout. The output voltage startup ramp is controlled by the SS/TRK pin which allows operation as either a standalone power supply or in tracking situations.
