MB39C313

The MB39C313 is designed as one kind of 4 ch DC/DC buck converter device that integrates all of necessary power supplies for Ultra-Mobile PC powered by 2-cell Li-ion battery. And this device is the Power Management IC supporting the LPIA(Low Power Intel Architecture) which Intel Corporation proposes as the low power consumption platform for UMPC. And it can be used in TFT LCD panels for LCD TV sets and monitors applications.

Features of the MB39C313 are:(1)Built-in soft-start circuit independent of loads; (2)Excellent line regulation by the feed-forward method (Vlogic, Vs); (3)Built-in phase compensator parts (Vlogic); (4)Built-in sequence comparator for rising; (5)Built-in short circuit protection (Vlogic); (6)Built-in over voltage protection (Vs); (7)Built-in over current protection (Vlogic, Vs); (8)Built-in over temperature protection; (9)Frequency setting by input pin: 500 kHz / 750 kHz; (10)Package: TSSOP-28 Exposed PAD; (11)Power supply voltage range: 8 V to 14 V; (12)Positive Charge Pump with output voltage feedback (VGH): 50 mA Max.etc.

The absolute maximum ratings of the MB39C313 can be summarized as:(1)Power supply voltage: -0.3 to +19.8 V;(2)Input voltage: -0.3 to +19.8 V;(3)SW Voltage: -0.3 to +19.8 V;(4)SW peak current: 3.9 or 4.2 A;(5)Power dissipation: VLX-0.3 to VCB V;(6)OUTL voltage: -0.3 to +7 V;(7)DIN voltage: 3.44 W;(8)Storage temperature: -55 to +125 °C.
