TDA38540 40 A DC-DC buck regulator features an onboard PWM controller and OptiMOS™ 5 FETs resulting in a very efficient, easy-to-use, compact VR solution. It enables stacking (up to 4) and can optionally sync to an external clock signal. TDA38540 provides extensive protection features such as pre-bias start up, UVP, OVP, etc. to give required system-level security in the event of fault conditions.

Features

  • Vin range from 3.0 to 17 V with ext Vcc
  • Vout range of 0.6 V to 6.0 V
  • Current mode control with fixed Fsw
  • Standalone or stackable operation
  • Programmable Fsw from 400 kHz - 2 MHz
  • Sync to an external clock signal
  • Voltage Moniotring with PGOOD
  • Comprehensive protection Features
  • -40°C to 150°C operation
  • Small size: 5 x 6 mm PQFN
  • Pb-free, RoHS2 (with exemption 7a)

Benefits

  • High efficiency and high power density
  • Excellent noise and jitter performance
  • Scalable up to 160 A, single Output VR
  • Stable and reliable VR
