Preliminary RT9268 Tiny Package, 1.3MHz, Step-up DC/DC Converter General Description The RT9268 is a compact, 1.3MHz, step-up DC/DC converter with a current mode PWM control loop, providing a stable and efficient operation without external compensation. The high switching frequency makes RT9268 suitable for ADSL applications providing sufficient output current for variant types of line drivers. This device is available in space-saving SOT-23-6 package. The output voltage is set with 2 external resistors. Both internal 2A switch and driver for driving external power devices (NMOS or NPN) are provided.
