The LM5017SD/NOPB is a synchronous buck regulator designed for a wide input voltage range of 7.5V to 100V, with a maximum output current of 600mA. It features integrated high-side and low-side MOSFETs, eliminating the need for an external Schottky diode. The device employs a constant on-time control scheme, which simplifies design by removing the need for loop compensation and provides fast transient response. The operating frequency can be adjusted up to 1 MHz, and the output voltage is adjustable down to 1.225V with a precision feedback reference of 2%. Additional features include intelligent peak current limiting, adjustable undervoltage lockout (UVLO), remote shutdown capability, and thermal shutdown protection. The LM5017 is available in two package options: WSON-8 and SO PowerPAD-8, making it suitable for various applications such as industrial programmable logic controllers, smart power meters, and telecom biasing. This regulator is particularly advantageous for designs requiring high step-down ratios and robust performance under varying input conditions.
