Switching Regulator |
eSR-Bu-1.62~3.63-0.8~3.3 is a inductor-based buck switching regulator designed to supply 0.8 to 3.3V rails in a wide range of applications. The integrated regulator is configurable before delivery to ensure optimized silicon area in applications requiring low-power loads. It can drive up to 600 mA with internal transistors and up to 5 A with external transistors.
It also features fully integrated active compensation circuitries which lower the bill-of-material as no additional external passive components are required.
SoC Providers and System Makers no longer need to worry about the embedded regulators in their SoC thanks to the additional Dolphin’s unique offering, AHM, for behavioral modeling of noise propagation in power networks.
