TLF50211ELV50 - 2.2MHz Step-Down Regulator

General Description

The TLF50211EL 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 V to 45 V makes the TLF50211EL suitable for a wide variety of applications.

Key Features

  • 500 mA step down voltage regulator.
  • 5 V Output voltage.
  • ±2% output voltage tolerance.
  • Low quiescent current (less than 45 µA at nominal battery voltage).
  • Integrated power transistor.
  • Current mode PWM regulation.
  • PFM mode for light load current.
  • Input voltage range from 4.75 V to 45 V.
  • 2.2 MHz switching frequency.
  • 100% Duty cycle.
  • Synchronization input.
  • Very low shutdown current consumptio.
