TLF502x1 devices reduce PCB-space and costs

This video introduces the new TLF502x1-family of Infineon’s automotive switch-mode power supplies. They are able to deliver up to 500mA with ultra-low current consumption. The design was performed to minimize the need of external components by integrated compensation and soft-start. Operation at high switching frequencies around 2.2MHz reduces coil and output capacitor size. The pin-compatible family approach provides devices with various features like ENABLE, RESET with adjustable threshold, and WATCHDOG with adjustable timing. 

TLF51801ELV with a current capability of up to 10A

The TLF51801 is an AEC-qualified high current buck-controller providing an adjustable
output voltage. The controller is capable to drive external power MOSFETs for load currents up to 10A. The current limitation can be realized either by sensing an external shunt resistor or by sensing the RDS(on) of the HS-switch reducing external components.
Very low drop-out operation is achieved by a maximum duty-cycle of more than 99%. The adjustable switching frequency in the range of 100 to 700kHz can be synchronized to an external clock. An Enable-feature allows very low shutdown current consumption. TLF51801 is coming in a small, thermal enhanced SSOP-14 exposed-pad package
(RoHS).
