The TLF50211EL is designed for automotive applications with a wide input voltage range of 4.75-45 V. Its 2.2 MHz switching frequency enables the use of small components, reducing output voltage ripple and board space. It operates in PFM for light loads, optimizing efficiency. It features protection functions, soft-start, and low power consumption in shutdown mode.

Features

  • 500 mA step down voltage regulator
  • 5 V Output voltage
  • ± 2% output voltage tolerance
  • Low quiescent current (less than 45μA at nominal battery voltage)
  • Current mode PWM regulation
  • PFM mode for light load current
  • Input voltage range from 4.75V to 45V
  • Integrated power transistor
  • 2.2 MHz switching frequency
  • 100% Duty cycle
  • Synchronization input
  • Very low shutdown current consumption (<2 μA)
  • Integrated compensation
  • Integrated soft-start function
  • Input undervoltage lockout
  • Suited for automotive applications: Tj = -40 °C to +150 °C
  • Green Product (RoHS compliant)
  • AEC Qualified
  • Pin-compatible family approach

Benefits

  • Low current consumption for permanently Vbat-connnected systems
  • High switching frequency reduces value and size of coil and output capacitor
  • Low drop-out operation due to 100% DC
  • No external components required for compensation and soft-start
  • One base design for multiple requirements by family approach
