YP6188

YP6188 1A Iout DC-DC Step-up Converter General Description The YP6188 is a high efficiency boost DC-DC converter which com bines a current mode, fixed frequency (1.22MHz or 640KHz programmable with FSEL pin) PWM architecture for TFT LCD displays and other portable applications. YP6188 operates over a wide range of input supply voltage(2.5Vvoltage (from VIN up to as high as 15V). The YP6188 also features a skip cycle mode operation for power saving at light loads. The built-in soft-start circuitry (externally programm able through the CSS pin) provides the freedom for the control of input current ramp rate.Overall current consum ption during the power down mode (by pull MPD~pin to logic low) is typically less than 0.1uA.Under-voltage lockout(UVLO),Thermal Shutdown (TSD), Over Current detection/protection (OVL) and other protection featuers are also incorporated onto the YP6188 to ensure the reliable operation under different operating circumsta...
