The LM2742MTCX/NOPB from Texas Instruments is a high-speed, synchronous, switching regulator controller designed for step-down (buck) applications. It operates with an input voltage range of 4.5V to 5.5V and can provide an adjustable output voltage down to 0.6V. This controller utilizes a fixed-frequency, voltage-mode, PWM control architecture, with a switching frequency adjustable from 50kHz to 2MHz.
Key features include an adjustable soft-start, a power good flag, and output enable for easy power sequencing. It also offers current limit without a sense resistor and a typical minimum on-time of 40ns. The device is housed in a 14-TSSOP package and operates within a temperature range of -40°C to 125°C.
With up to 95% conversion efficiencies, the LM2742MTCX/NOPB is suitable for controlling currents from 0.7A to 20A. Its flexible operating frequency allows power supply designers to fine-tune component size, cost, noise, and efficiency. The adaptive, non-overlapping MOSFET gate-drivers and high-side bootstrap structure further enhance efficiency.
