Description
High-Speed Response DC-DC Step Down Regulator Circuit that employs Hysteretic Control System - Built-in inductor and capacitors - Skip (discontinuous) Mode for high efficiency at light load Maximum Output Current : 10 A - Input Voltage Range : PVIN=AVIN = 4.5 V to 28 V, Output Voltage Range : 0.6 V to 5.5 V Selectable Switching Frequency 400 kHz / 600 kHz / 800 kHz - Built-in Feed Back Resistors for 1.0 V / 3.3 V default settings Configurable output voltage settings using external Resistors - Adjustable Soft Start - Low Operating and Standby Quiescent Current - Open Drain Power Good Indication for Output Over / Under Voltage - Selectable Auto recovery / latch off protection system - Adjustable current limit threshold - Built-in Under Voltage Lockout (UVLO), NN31000A is a synchronous DC-DC step down regulator (1-ch), Power Supply in Package (PSiP), which integrates a Controller IC that employs a hysteretic control system, two Power MOSFETs, an Inductor and Capacitors into a single 8.5 x 7.5 x 4.7mm QFN package. The easiness of mounting PSiP onto a Printed Circuit Board (PCB), a very small footprint and a highly reduced number of external components, offers very compact and simplified solutions for applications requiring pointof-load design.
