General Description
The LM2742 is a high-speed, synchronous, switching regulator controller.
It is intended to control currents of 0.7A to 20A with up to 95% conversion efficiencies.
Key Features
- The LM2742 operates from a low-current 5V bias and can convert from a 1V to 16V power rail. The part utilizes a fixedfrequency, voltage-mode, PWM control architecture and the switching frequency is adjustable from 50kHz to 2MHz by setting the value of an external resistor. Current limit is achieved by monitoring the voltage drop across the onresistance of the low-side MOSFET, which enables on-times on the order of 40ns, one of the best in the industry. The wide range of operating frequencies gi.
