Pin Description Pin Number Pin Name Function A1 FB Feedback Analog Input. B1 EANEG Inverting input of error amplifier C1 EAOUT Output of error amplifier D1 SYNC/MODE Synchronization Input. Use this digital input for frequency selection or modulation control. Set: SYNC/MODE = high for low-noise 600kHz PWM mode SYNC/MODE = low for low-current PFM mode SYNC/MODE = a 500kHz–1MHz external clock for synchronization in PWM mode. (See Synchronization and Operating Modes in the Device Information section.) D2 EN Enable Input. Set this Schmitt trigger digital input high for normal operation. For shutdown, set low. Set EN low during system power-up and other low supply voltage conditions. (See Shutdown Mode in the Device Information section.) D3 PGND Power Ground C3 SW Switching Node connection to the internal PFET switch and NFET synchronous rectifier. Connect to an inductor with a saturation current rating that exceeds the max Switch Peak Current Limit of the LM2614. B3 PVIN Power Supply Voltage Input to the internal PFET switch. Connect to the input filter capacitor. A3 VDD Analog Supply Input. If board layout is not optimum, an optional 0.1µF ceramic capacitor is suggested.
