该评估板提供了检查高效率LM21215降压型开关稳压器的解决方案。The LM21215 is capable of driving up to 15A of continuous load current with excellent 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 500 kHz. 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 startup response of the LM21215, and the precision enable pin can be used to easily sequence the LM21215 in applications with sequencing requirements.
