4ch System Power Management IC for

LCD Panel

MB39C313

■ DESCRIPTION

■ FEATURES

■ APPLICATIONS

The MB39C313 is a 4ch system power management IC. It consists of 2-ch DC/DC Converter and 2-ch

Charge pump. The DC/DC converter has excellent line regulation with the feed-forward method. Moreover,

SW FET and phase compensator (Buck) is included, so that BOM can be reduced. It is most suitable for

large size LCD panel power supply.

• Power supply voltage range: 8 V to 14 V

• For Buck Converter included SW FET (Vlogic): output 1.8 V to 3.3 V 1.5 A Max

• For Boost Converter included SW FET (Vs): output 18.1 V Max 1.5 A Max (at 12 V input and 15 V output)

• Negative Charge Pump with output voltage feedback (VGL): 50 mA Max

• Positive Charge Pump with output voltage feedback (VGH): 50 mA Max

• Error Amp threshold voltage: 1.213 V ± 1.5 % (Vlogic), 1.146 V ± 0.9 % (Vs),0 V ± 36 mV (VGL),

• Built-in soft-start circuit independent of loads

• Excellent line regulation by the feed-forward method (Vlogic, Vs)

• Built-in phase compensator parts (Vlogic)

• Built-in sequence comparator for rising

• Built-in short circuit protection (Vlogic)

• Built-in over voltage protection (Vs)

• Built-in over current protection (Vlogic, Vs)

• Built-in over temperature protection

• Frequency setting by input pin: 500 kHz / 750 kHz

• Package: TSSOP-28 Exposed PAD

TFT LCD panels for LCD TV sets and monitors.
