The iW1690 is a high performance AC/DC power supply controller which uses digital control technology to build peak current mode PWM flyback power supplies. The device directly drives a BJT switching device and provides high efficiency along with a number of key built-in protection features while minimizing the external component count, simplifying EMI design.
• Primary-side feedback eliminates opto-isolators and simplifies design
• Direct drive of BJT switching device
• Multi-mode operation for highest overall efficiency
• Built-in cable drop compensation
• Very tight output voltage regulation
• No external compensation components required
• Complies with CEC/EPA no load power consumption and average efficiency regulations
• Built-in output constant-current control with primary-side feedback
• Low start-up current (10 µA typical)
• Built-in soft start
• Built-in short circuit protection and output overvoltage protection
• Optional AC li.
