MB39C313 Datasheet | Fujitsu Semiconductor Limited

FUJITSU MICROELECTRONICS DATA SHEET DS04- 27267- 1E ASSP for Power Management Applications of LCD Panel 4ch System Power Management IC for LCD Panel - DESCRIPTION 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 pensator (Buck) is included, so that BOM can be reduced. It is most suitable for large size LCD panel power supply. - Features - - - - - - - - - - - - - - - - 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 m A Max Positive Charge Pump with output voltage feedback (VGH): 50 m A Max Error Amp threshold voltage: 1.213 V ± 1.5 % (Vlogic), 1.146 V ± 0.9 % (Vs),0 V ± 36 m V (VGL), 1.213 V ± 2.1 % (VGH) Built-in soft-start circuit independent of loads Excellent line regulation by the feed-forward method (Vlogic, Vs) Built-in phase pensator parts (Vlogic) Built-in sequence parator 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 k Hz / 750 k Hz Package: TSSOP-28 Exposed PAD - APPLICATIONS TFT LCD panels for LCD TV sets and monitors.
