R1290K SERIES 3ch DC/DC for TFT LCD No.EA-154-210517 OUTLINE The R1290 series are the optimized DC/DC converter ICs for TFT LCD displays. Each of the R1290 series contains one PWM step-up DC/DC converter controller and two diode charge-pump controllers. The charge-pumps can control a boost output and a negative output and have the output voltage regulation function with external resistors. The power on sequence can be made with setting the delay time with external capacitors for each charge pump channel. FEATURES • Operating Voltage Range ...................................... 2.0V ~ 5.5V • Step-up DC/DC controller part Internal 2A capability Nch MOSFET Driver (RON=150mΩ Typ.
