The AP1502 series are monolithic IC's containing a PWM and a linear power controller. The PWM regulator has an ability of driving a 1A load without additional external transistors. Due to the reduced the number of external components, board space can be saved easily. The external shutdown function can be controlled by logic level and switching the IC into standby mode. The internal compensation provides a good line and load regulation without external components. Regard the protecting functions: Thermal shutdown is to prevent the IC from damage by operating on over temperature, and current limit is against over current in the output switch. The AP1502 series operates at a switching frequency of 200KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed +2% tolerance on output voltage under specified input voltage and output load conditions, and +10% on the oscillator frequency. The version range included for the PWM part fixed output voltages of 3.3V, 5V, 12V, and an adjustable version. The linear controller is able to drive an external NPN transistor, which a current limit set to 30mA pre-driver of AP1502 series. The IC's are available in a standard SOP7 package for AP1502. |
