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.
5VVIN5.
5V) and provides a regulated boost
voltage (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.
