Additional Details:

The MP3406DS-LF-Z employs a current-mode control architecture for stable operation. The internal soft-start function limits inrush current during startup. Over-voltage protection (OVP) protects the output from exceeding the specified voltage limit. Short-circuit protection (SCP) prevents damage during short circuit events. Over-temperature protection (OTP) shuts down the device when the junction temperature rises above a safe level. The device is available in a compact TSOT23-5 package. The 1.2MHz switching frequency reduces the size of external inductor and capacitor. This product is lead-free and RoHS compliant.
