The TLF50241EL is designed for harsh automotive environments with a wide input voltage range of 4.75 V to 45 V. Its 2.2 MHz nominal switching frequency enables the use of small and cost-effective components, reducing output voltage ripple and board space consumption. In light load conditions, the device operates in Pulse Frequency Modulation (PFM) mode to optimize efficiency by minimizing internal power consumption during idle periods.

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
  • Integrated compensation
  • Integrated soft-start function
  • Reset generator with adjustable threshold
  • 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
  • Flexibility in setting reset threshold
  • One base design for multiple requirements by family approach
