RAA211450 Datasheet DC/dc Synchronous Step-down Regulator

Manufacturer: Renesas

Overview: Datasheet RAA211450 4.5V to 42V, 5A, DC/DC Synchronous Step-Down Regulator w/ Internal Compensation and Adjustable Frequency The RAA211450 is a DC/DC synchronous step-down (Buck) regulator that supports a 4.5V to 42V input voltage range and adjustable output voltage. It can deliver up to continuous 5A of continuous output current with premium load and line regulation performance. The RAA211450 uses peak-current mode control architecture. Its PWM switching frequency is programmable to provide the best trade-off between transient response and efficiency. It also supports PFM operation and DEM to maximize light load efficiency, in addition to an external bias LDO input to further reduce power dissipation across the load range. The regulator also has an internal loop compensation circuit to reduce the external component count and BOM cost. The RAA211450 provides useful functions such as internal or programmable soft-start and power good indicator.
