DC converter touts compensated control
ACM is an emulated peak-current-mode control topology that internally generates a ramp with the ability to dynamically adjust for stability over a wide range of operating switching frequencies. This provides the best of both conventional fixed frequency for low-noise operation and constant on-time control for fast transient response without external compensation. ACM control maintains stability over an input voltage range of 4 V to 16 V and an output voltage range of 0.6 V to 5.5 V.
The TPS543C20 provides greater than 90% efficiency at a peak load current of 40 A. It also offers full differential remote-voltage sensing to meet the voltage accuracy requirements of deep submicron processors and maintains 0.5% reference voltage accuracy over temperature.
Housed in a 40-pin, 5×7×1.5-mm PowerStack QFN package, the TPS543C20 costs $5.24 each in lots of 1000 units on small reels.
