The TLF50251EL from Infineon Technologies is a high-frequency PWM step-down DC/DC converter designed for automotive applications. It provides a stable 5V output voltage with a current capability of 500 mA and an output voltage tolerance of ±2%.
Key electrical features include a wide input voltage range from 4.75V to 45V, a switching frequency of 2.2 MHz, and a low quiescent current of less than 45 µA at nominal battery voltage. For light load conditions, it operates in Pulse Frequency Modulation (PFM) mode to optimize efficiency. The device also includes a soft-start function and a reset generator.
Packaged in a PG-SSOP-14 with an exposed pad, the TLF50251EL is designed for surface mount applications. Its design under harsh automotive environmental conditions and features like integrated power transistor, cycle-by-cycle current limitation, overtemperature shutdown, and input undervoltage lockout make it suitable for demanding applications.
The TLF50251EL has a nominal output voltage of 5V.
The TLF50251EL can provide up to 500 mA of output current.
The input voltage range for the TLF50251EL is from 4.75V to 45V.
The TLF50251EL operates at a nominal switching frequency of 2.2 MHz.
The quiescent current of the TLF50251EL is less than 45 µA at nominal battery voltage.
The TLF50251EL is available in a PG-SSOP-14 package.
The operating junction temperature range for the TLF50251EL is -40°C to 150°C.
