Infineon Technologies AG DC-DC Converters, Switching Regulators TLF50241EL

Description
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 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 Potential Applications Body Cluster Infotainment General purpose replacement of LDO Family Overview For an overview of other available options in this family please click here.
