YP6188 1A Iout DC-DC Step-up Converter

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(2.5V

YP6188 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 typi
