TLE8366EV Description

Short technical summary and product information.

The Infineon TLE8366EV is a PWM step-down DC/DC converter with an integrated 1.8A power switch, packaged in a PG-DSO-8 with an exposed pad. It offers output voltage versions of 5.0 V, 3.3 V, and an adjustable option with a reference feedback voltage of 600 mV.

The device supports a wide input voltage range from 4.75 V to 45 V, making it suitable for various applications, especially under harsh automotive environments. The nominal switching frequency is 370 kHz, which allows for the use of small, cost-effective inductors and capacitors, minimizing board space and output ripple.

Safety features include cycle-by-cycle current limitation, over-temperature shutdown, and input undervoltage lockout. The TLE8366EV also includes a soft-start function to limit inrush current during startup and an enable function for power management, consuming less than 2 µA in shutdown mode.

This regulator is designed for automotive applications and operates within a junction temperature range of -40 °C to +150 °C. It is AEC Qualified and RoHS compliant.
