Learn about this evaluation board that could be used to examine the efficiency LM21215 buck switching regulator. The LM21215 is capable of driving up to 15A of continuous load current with output voltage accuracy due to its ±1% internal reference. The LM21215 is capable of down converting from an input voltage between 2.95V and 5.5V at a fixed switching frequency of 500kHz. This device also features an adjustable current limit that allows the user to set the internal current limit protection value. Other fault protection features include output power good and output over-voltage protection. The dual function soft-start/tracking pin can be used to control the start-up response of the LM21215, and the precision enable pin can be used to easily sequence the LM21215 in applications with sequencing requirements.
