This evaluation board provides a solution to examine the high efficiency LM21212-1 buck switching regulator. The LM21212-1 is capable of driving up to 12A of continuous load current with excellent output voltage accuracy due to its ±1% internal reference. This device also features a clock synchronization input that allows the switching frequency to be synchronized to an external clock source. The 300 kHz to 1.5 MHz frequency synchronization range enables the user to minimize the power stage component size, while still allowing for high efficiency. The LM21212-1 is capable of down converting from an input voltage between 2.95V and 5.5V. Fault protection features include current limit, output power good and output over-voltage protection. The dual function softstart/tracking pin can be used to control the startup response of the LM21212-1, and the precision enable pin can be used to easily sequence the LM21212-1 in applications with sequencing requirements.
