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 4.75V to 45V 370 kHz switching frequency Synchronization input Very low shutdown current consumption (<2uA) Soft-start function Input undervoltage lockout Suited for automotive applications: Tj = -40 °C to +150 °C Green Product (RoHS compliant) AEC Qualified PG-DSO-8 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. The device is designed to be used under harsh automotive environment. The switching frequency of nominal 370 kHz allows the use of small and cost-effective inductors and capacitors, resulting in a low, predictable output ripple and in minimized consumption of board space. (If desired the device could be synchronized t...
