TLE8366 Datasheet 1.8a DC/dc Step-down Voltage Regulator

Manufacturer: Infineon

Overview: TLE8366 1.8A DC/DC Step-Down Voltage Regulator TLE8366EV50 TLE8366EV TLE8366EV33 Data sheet Rev. 1.0, 2009-05-18 Automotive Power 1.8A DC/DC Step-Down Voltage Regulator TLE8366 1 Overview • 1.8A step down voltage regulator • Output voltage versions: 5.0 V, 3.3 V and adjustable • ± 2% output voltage tolerance (+-4% for full load current range) • Integrated power transistor • PWM regulation with feedforward • Input voltage range from 4.

General Description

The TLE8366 is a PWM step-down DC/DC converter with an integrated 1.8 A power switch, packaged in a small PG-DSO-8 with exposed pad.

There are three versions available, two fixed voltage with 5.0 V (TLE8366EV50) or 3.3 V (TLE8366EV33) and a variable voltage variant named TLE8366EV with a reference feedback voltage of only 600 mV.

The wide input voltage range from 4.75 to 45 V makes the TLE8366 suitable for a wide variety of applications.

Key Features

  • such as a cycle-by-cycle current limitation, over-temperature shutdown and input under voltage lockout. The enable function, in shutdown mode with less than 2 µA current consumption, enables easy power management in battery-powered systems. The voltage regulation loop provides an excellent line and load regulation. The stability of the loop could be adjusted by using an external compensation network. This compensation network combined with voltage mode regulation and a feed-forward control path.
