The RT9266B is a compact, high efficiency, and low
voltage step-up DC/DC converter with an Adaptive
Current Mode PWM control loop, includes an error
amplifier, ramp generator, comparator, switch pass
element and driver in which providing a stable and high
efficient operation over a wide range of load currents. It
operates in stable waveforms without external
compensation.
The low start-up input voltage below 1V makes RT9266B
suitable for 1 to 4 battery cells applications with a 500mA
internal switch. The 550kHz high switching rate minimized
the size of external components. Besides, the 25μA low
quiescent current together with high efficiency maintains
long battery lifetime.
