DESCRIPTION
NN31001A 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.

FEATURES

● 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 / 800kHz
● 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),
   Thermal Shut Down (TSD), Under Voltage Detection (UVD),
   Over Voltage Detection (OVD), Short Circuit Protection (SCP)
   Over Current Protection (OCP)
● Plastic Quad Flat Non-leaded Package Heat Slug Down
   (QFN Type, Size : 8.5 mm  7.5 mm, 0.5 mm pitch)
