Rev.1.1 Nov 17, 2004 Features - Provides two regulated voltages -one PWM Controller( Drive PMOS) -one Linear Controller (Drive NPN and NMOS) - Adjustable version: 1.23+/- 2.5%. - 250KHz +10% fixed switching frequency - Thermal-shutdown and current-limit protection - SS/EN Soft-Start/Enable Function. - Operating voltage can be up to 22V - Low power standby mode - Pb-Free Package: SOP8,DIP8 Applications - Simple High-efficiency step-down regulator - On-card switching regulators - XDSL… General Descriptions The AP2006 series are monolithic IC’s containing a PWM and a linear power controller. The PWM driving a external PMOS. Due to the reduction of the number of external components, board space can be saved easily. The external shutdown function can be controlled by logic level. It switchs the IC into the standby mode. The internal compensation provides a good line and load regulation without external component. Short circuit protection prohibits the over current in the output switchs. The AP2006 series operate at the switching frequency of 250KHz. Therefore, it is able to use the smaller sized filters than what used to be used with the lower frequency switching regulators. Other features include a guaranteed + 3% tolerance on output voltage under specified input voltage and output load conditions, and + 20% on the oscillator frequency. The linear controller is able to drive an external NPN transistor, with 30mA current limit pre-driver. The ICs are available in a standard SOP8/DIP8 package. Pin Assignments AP2006
