PRODUCTION DATA.
デバイスごとのパッケージ図は、PDF版データシートをご参照ください。
The LMZ21700 has integrated protection against heavy loads and output short circuit events. Both, the high-side FET and low-side FET have current monitoring circuitry. If the current limit threshold of the high-side FET is reached , the high-side FET will be turned off and the low-side FET will be turned on to ramp down the inductor current. Once the current through the low-side FET has decreased below a safe level, the high-side device will be allowed to turn on again. The actual DC output current depends on the input voltage, output voltage, and switching frequency. Refer to the Application Curves section for more information.
