illustrate

The LM2742 is a high-speed, synchronous, switching regulator controller. It is designed to control current conversion efficiency from 0.7A to 20A up to 95%. Power and power off sequencing are good signs of implementation with power supply, adjustable soft start and output enable functions. The LM2742 operates from a low-current 5V bias and can be converted to a 1V to 16V power rail. The partially adopts a fixed frequency, voltage mode, PWM control architecture and switching frequency adjustable from 50kHz to 2MHz by setting an external resistance value. The current limit is a low-side MOSFET that monitors the voltage on-resistance at both ends, bringing the order drop to 40ns, one of the best in the industry. The wide operating frequency range gives power supply designers the flexibility to fine-tune component size, cost, noise, and efficiency. Adaptive non-overlapping MOSFET gate drivers and high-side guide structures help further maximize efficiency. The drain voltage of the high-side power FETs is available from 1V to 16V, and the output voltage can be adjusted as low as 0.6V.
