YP6188 Overview
The YP6188 is a high efficiency boost DC-DC converter which 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<VIN<5.5V) and provides a regulated boost voltage (from VIN up to as high as 15V).
