Conv DC-DC Single Step Down 4.75V to 45V 14Pin SSOP T/R
Description:
The TLF50281EL 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 TLF50281EL 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. 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 in rush current peak and prevents from an output voltage overshoot. The TLF50281EL includes protection features such as a cycle-by-cycle current limitation, over-temperature shutdown and input under voltage lockout.
