LV5099CB

www.DataSheet.co.kr Ordering number : ENA1991 Bi-CMOS LSI LV5099CB Overview Features and Functions For HDMI controller Charge pump power supply The LV5099CB is a charge pump power supply for HDMI controllers for portable devices. Features 5.0V and 3.3V constant voltage outputs composed of 2-hold mode charge pump boost circuit. Built-in overload detection function for constant voltage output circuit. Overcurrent limit (70mA) operates with 1.5Ω external resistor. Constant voltage output after time-latch: OFF (100msec). Reverse flow prevention function is built into constant voltage output. (An external diode for reverse flow prevention is not necessary.) There is no reverse current from 5.0V output to VCC. The current flow into 3.3V output is less than 1µA, when EN: Low Ultra-small chip package (Those with backcourt processing (those with a resin tabulation side protective film)) Function Charge pump circuit. 2-hold mode Constant voltage output. 3.3V output/10mA(max) 5.0V output/60mA(max) Thermal shutdown Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum power supply voltage Maximum DC voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC V1 max Pd max Topr Tstg C+ CPOUT VO50 VO33 with specified substrate * Conditions Ratings 4.8 6 0.75 -30 to +85 -55 to +125 Unit V V W °C °C * : Specified substrate : 50mm×50mm×1.6mm, glass epoxy board Caution 1) Absolute maximum ratings represent the value which can...
