The RT9266 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 RT9266
suitable for 1 to 4 battery cells applications of providing
up to 300mA output current. The 450kHz high switching
rate minimized the size of external components. Besides,
the 17uA low quiescent current together with high
efficiency maintains long battery lifetime.
The output voltage is set with two external resistors. Both
internal 2A switch and driver for driving external power
devices (NMOS or NPN) are provided.
