The easiness of mounting PSiP onto a Printed Circuit  Input Voltage Range : PVIN=AVIN = 4.5 V to 28 V, Board (PCB), a very small footprint and a highly reduced Output Voltage Range : 0.6 V to 5.5 V number of external components, offers very compact Selectable Switching Frequency 400 kHz / 600 kHz / 800 kHz and simplified solutions for applications requiring point Built-in Feed Back Resistors for 1.0 V / 3.3 V default settings of-load design. Configurable output voltage settings using external Resistors The number of external components have been reduced to only input/output capacitor, slow start capacitor and  Adjustable Soft Start feedback resistors.  Low Operating and Standby Quiescent Current Furthermore, for applications requiring an output voltage  Open Drain Power Good Indication for Output Over / Under of 1.0 V / 3.3 V, the external feedback resistors can be Voltage eliminated, resulting into even a smaller footprint.  Selectable Auto recovery / latch off protection system The PSiP achieves efficiencies of greater than 95 % with  Adjustable current limit threshold very good power dissipation capabilities.  Built-in Under Voltage Lockout (UVLO), Thermal Shut Down (TSD), Under Voltage Detection (UVD), APPLICATIONS Over Voltage Detection (OVD), Short Circuit Protection (SCP) High Current Distributed Power Systems such as Over Current Protection (OCP) ・DSP and FPGA Point-of-Load Applications  Plastic Quad Flat Non-leaded Package Heat Slug Down ・Routers (QFN Type, Size : 8.5 mm  7.5 mm, 0.5 mm pitch) ・Industrial Equipment M ma ain int ten en an an ce ce /D typ isc e, ont ma inu Efficiency [%] int ed en in an clu ce de typ s f e, ollo pla wi ne ng d d fou isc r P on rod tin uc ue t l d t ife yp cy ed cle , d st isc ag on e. tin ue dt yp e) M Di ain sc te on na tin nc ue e/ d  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 ・Space constrained Applications etc. SIMPLIFIED APPLICATION 100 VREG 90 PVIN EN PGOOD PRTCNT BST LX OCPCNT (p MODE VFB 1.5k FSEL VOUT = 1.0V VOUTM #1.0V / 3.3V AGND1, 2 PGND VOUT=1V, Fsw=400kHz 60 VOUT=1V, Fsw=600kHz VOUT=1V, Fsw=800kHz without using FB resistor VOUT SS 70 VREG NN31000A 1k 80 ed AVIN lan 10µF x 2 VIN 100k 50 VOUT=3.3V, Fsw=600kHz 22µF x 3 4.7nF Note : The application circuit is an example.
