AP8024
AC-DC PWM CONTROLLER NON-ISOLATED PWM CONVERTERS
DESCRIPTION
FEATURES
The AP8024 consists of an integrated Pulse Width Modulator (PWM) controller and power MOSFET, specifically designed for small power non-isolated switching power supply. AP8024 offers fully intelligentized protection including Cycle-by-Cycle current limiting (OCP); Over Voltage Protection (OVP), Over Load Protection (OLP), Under Voltage Lockout and Over Temperature Protection (OTP). Excellent EMI performance is achieved with Pulse Frequency Modulation. AP8024 also consists of the high voltage start-up circuit to ensure that start quickly. The application need less component device.
AP8024 is available in a DIP7 package.
Be optimized with 12V output non-isolated application 85~265VAC wide input voltage scope Frequency modulation for low EMI Internal HV Start-up Circuit Open frame output power >4.5W @230VAC Excellent constant voltage regulation and High efficiency Excellent Protection Coverage: Adjustable Over Current Protection(OCP) Over Temperature Protection(OTP) Over Load Protection(OLP) Over voltage protection (OVP) Available in a DIP7 package.
