The AEC-Q100 qualified TLF12501integrated power stageis a member of theOPTIREG™ multiphase product familyand is optimized to fit to requirements derived from the automotive segment by utilizing a new unique package for improved thermal-cycle and long-term reliability and robustness. It contains a low quiescent currentsynchronous buck gate-driver ICwhich is co-packed with control and synchronous MOSFETs. The package is optimized for reliability in harsh automotive environment, PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing. The paired gate driver and MOSFET combination enables high efficiency at lower output voltages required by cutting edge CPU, GPU and DDR memory designs. The internal MOSFET sensing achieves superior current sense accuracy vs. best-in-class controller-based inductor DCR sense methods. Protection includes IC temperature reporting and over temperature protection feature (OTP with thermal shutdown), cycle-by-cycle over current protection (OCP), control MOSFET short detection (HSS - high side short detection), VDRV and bootstrap under-voltage protection. The TLF12501 also features "refreshing" of bootstrap capacitor to prevent the bootstrap capacitor from over-discharging. Operation of up to 2 MHz switching frequency enables high performance transient response, allowing miniaturization of output inductors, as well as input and output capacitors while maintaining industry leading efficiency. The TLF12501 is compatible with 3.3 V tri-state PWM input signal.
