NAME Voltage control analog input. VCON controls VOUT in PWM and ECO modes. VCON may also A1 VCON Analog be used to force the device into sleep mode by setting VCON < 80 mV or into bypass condition by setting VCON > 1.5 V. A2 SGND Ground Signal ground for analog and control circuitry. A3 PGND Ground Power ground for the Power MOSFETs and gate drive circuitry Enable Input. Set this digital input high for normal operation. For shutdown, set low. Do not B1 EN Digital/Input leave EN pin floating. B2 NC — Do not connect to PGND directly — Internally connected to SGND. Switching node connection to the internal PFET switch and NFET synchronous rectifier. B3 SW Analog Connect to an inductor with a saturation current rating that exceeds the maximum switch peak current limit specification of the LM3262. Bypass enable input. Set this digital input high to force bypass operation. For normal operation C1 BPEN Input with automatic bypass, set low or connect to ground. Do not leave this pin floating. Feedback analog input and bypass FET output. Connect to the output at the output filter C2 FB Analog capacitor. C3 VIN Input Voltage supply input for SMPS converter.
