The R7732LGE from RICHTEK is an enhanced, high-performance current-mode PWM controller, serving as a successor to the R7730/1 series. It is designed for "easy to design" applications, aiming to reduce design effort and the number of external components required. This controller integrates a wide range of protection features, including internal Over Load Protection (OLP) and Over Voltage Protection (OVP), as well as Secondary Rectifier Short Protection (SRSP) and CS pin open protection, enhancing PSU reliability and safety.
The R7732LGE is suitable for cost-effective and compact power supply designs, such as NB adaptors. It supports features like UVLO (9V/14V), Soft-Start, Current Mode Control with built-in slope compensation, and internal leading edge blanking. The controller also offers PWM Quadruple Mode for Green-Mode operation and excellent green power performance, along with cycle-by-cycle current limiting. Additional protections include opto-coupler short protection and feedback open-loop protection. The device incorporates a built-in jittering frequency and a PRO pin for external arbitrary OVP/OTP implementation. Soft driving is included to minimize EMI noise, and it boasts high noise immunity.
Packaged in a SOT-23-6 surface-mount package, the R7732LGE is RoHS Compliant and Halogen Free, making it suitable for environmentally conscious designs. Its applications include switching AC/DC adaptors, battery chargers, printer power supplies, DVD open frame power supplies, Set-Top Boxes (STB), ATX standby power, TV/monitor standby power, PC peripherals, and NB adaptors.
