Overview
® R7732 Enhanced PWM Flyback Controller General Description R7732 series is the successor of R7730/1 and fully compatible with most of SOT-23-6 product so far in the market.
It's an enhanced, high-performance and current mode PWM controller.
It focuses on "easy to design" in different applications and it will save both design effort and external components.
Besides the general features shown in the Features section, R7732 covers wide protection options, such as internal Over Load Protection (OLP) and Over Voltage Protection (OVP) to eliminate the external protection circuits.
Moreover, it also features Secondary Rectifier Short Protection (SRSP) and CS pin open protection.
This protection will make the PSU design for reliability and safety easier.
R7732 is designed for power supply such as NB adaptor which is a very cost effective and compact design.
The precise external OVP and Over Temperature Protection (OTP) can be implemented by very simple circuit.
The start-up resistors can a...
