Wide-range buck dc-dc drops 6-75Vin to 0.8-60Vout


An input range of 6V to 75V is the eye-catching spec of STMicroelectronics’ L3751 synchronous buck controller, and many of its inputs can tolerate 100V. Its has a constant-frequency voltage-mode architecture, with its output voltage compared to an 800mV internal reference through a feedback pin. Input voltage feed-forward is implemented to improve line transient response. …
