DC-DC 5V 500mA PG-SSOP-14 D SMD Description

The TLF50241EL is a high frequency PWM step-down DC/DC converter with an integrated PMOS power switch, packaged in a small PG-SSOP-14 with exposed pad. The wide input voltage range from 4.75 to 45 V makes the TLF50241EL suitable for a wide variety of applications. The device is designed to be used under harsh automotive environmental conditions. The switching frequency of nominal 2.2 MHz allows the use of small and cost-effective inductors and capacitors, resulting in a low, predictable output voltage ripple and in minimized consumption of board space. In light load condition the device operates in Pulse Frequency Modulation (PFM) to optimize the efficiency. Between the single pulses, all internal controlling circuitry is switched off to reduce the internal power consumption.

Summary of 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
