illustrate

The LM2742 is a high-speed, synchronous, switching regulator controller. It is designed to control up to 95% conversion efficiency of 0.7A current 20A. The upper and lower sequencing of the power supply achieves good marking with the power supply, and the adjustable soft start and output enable functions. The LM2742 operates at a low current 5V bias and can be converted from 1V to 16V rails. The device adopts a fixed frequency, voltage mode, PWM control structure, and the switching frequency is adjustable by setting an external resistor from 50kHz to 2MHz. The current limit is monitored by spanning the low-side MOSFET, which can be used to drop the voltage of the industry's leading first-order on-resistor at 40ns. Fine-tuned component size, cost, efficiency, noise, and flexibility for power supply designers with a wide operating frequency range. Adaptive non-overlapping MOSFET gate drivers and high-side guide structures help further improve efficiency. The drain voltage of the high-side power FET can be from 1V to 16V, and the output voltage can be adjusted as low as 0.6V.
