LM21215A-1 15A High Efficiency Synchronous Buck Regulator with Frequency Synchronization
General Description
The LM21215A-1 is a monolithic synchronous buck regulator that is capable of delivering up to 15A of continuous output current while producing an output voltage down to 0.6V with outstanding efficiency.

The device is optimized to work over an input voltage range of 2.95V to 5.5V, making it suited for a wide variety of low voltage systems. The voltage mode control loop provides high noise immunity, narrow duty cycle capability and can be compensated to be stable with any type of output capacitance, providing maximum flexibility and ease of use. The LM21215A-1 features internal over voltage protection (OVP) and over-current protection (OCP) for increased system reliability. A precision enable pin and integrated UVLO allow turn-on of the device to be tightly controlled and sequenced. Startup inrush currents
