The MAX5070AAUA+ is a BiCMOS, high-performance, current-mode PWM controller from Analog Devices Inc. It is suitable for wide input voltage range isolated and non-isolated power supplies, including universal input AC/DC, telecom, and industrial applications.
Key features include a fast comparator with a typical 60ns delay from current sense to output for overcurrent protection. The switching frequency is adjustable from 20kHz to 1MHz using an external resistor and capacitor. The device also offers a low 32µA startup current and a 5V VREF output with 20mA capability.
This controller is available in 8-pin µMAX and SO packages and operates over an automotive temperature range of -40°C to +125°C. It is pin-for-pin compatible with UC2842 and UC2844 controllers.
The MAX5070AAUA+ is designed for applications such as universal input AC/DC power supplies, isolated telecom power supplies, networking systems, computer systems/servers, and industrial power conversion.
