TLF50241EL Datasheet 2.2 Mhz Step-down Regulator

Manufacturer: Infineon

Overview: TLF50241EL 2.2 MHz Step-Down Regulator 500 mA, 5 V, low quiescent current Data Sheet Rev. 1.0, 2013-06-19 Automotive Power 2.2 MHz Step-Down Regulator 500 mA, 5 V Low quiescent current TLF50241EL TLF50241EL 1 Overview • 500 mA step down voltage regulator • 5 V Output voltage • ± 2% output voltage tolerance • Low quiescent current (less than 45µA at nominal battery voltage) • Integrated power transistor • Current mode PWM regulation • PFM mode for light load current • Input voltage range from 4.75V to 45V • 2.

General 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.

Key Features

  • such as a cycle-by-cycle current limitation, over-temperature shutdown and input under voltage lockout. The voltage regulation loop provides an excellent line and load regulation, the stability of the loop is ensured by an internal compensation network. This compensation network combined with a current mode regulation control guarantees a highly effective line transient rejection. During start-up the integrated soft-start limits the inrush current peak and prevents from an output voltage oversho.
