ACT4751M Description
The ACT4751M is a programmable DC-to-DC buck converter with bias supply rails. This synchronous stepdown voltage regulator supports a wide input voltage of 4.5 V to 40 V and integrates both the high side and low side MOSFETS. These 50mΩ RDSON transistors enable high efficiency by reducing power losses.
