Pin Description PIN NAME FUNCTION
1 BST High-Side Driver Supply. Connect a 0.1µF bootstrap capacitor between LX and BST. 2 SUP IC Supply Input. Connect a minimum of 4.7µF ceramic capacitor from SUP to PGND. 3 LX Buck Switching Node. LX is high impedance when the device is off. 4 PGND Power Ground. Connect to AGND under the device in a star configuration. 5 AGND Analog Ground. Connect to PGND under the device in a star configuration. 6 RESET Open-Drain Reset Output. An external pullup resistor is required. 7 MODE Mode Switch-Control Input. Connect to ground or leave open to enable skip-mode operation under light loads. Connect to BIAS to enable forced-PWM mode. MODE has a 1MΩ internal pulldown. 8 BIAS 5V Internal Logic Supply. Connect a 1µF ceramic capacitor to AGND. MAX16956A/B/D/E (Fixed Output): Buck Regulator Voltage-Sense Input. Bypass OUT to PGND with a 9 OUT/FB minimum 22µF X7R ceramic capacitor. MAX16956C/F (Adjustable Output): Feedback Input. Connect FB to a resistive divider between the buck output and AGND to set the output voltage. 10 EN SUP Voltage-Compatible Enable Input. Drive EN low to disable the device. Drive EN high to enable the device. — EP Exposed Pad. Connect EP to a large copper ground plane for effective power dissipation. Do not use EP as the only IC ground connection. EP must be connected to PGND. www.maximintegrated.com Maxim Integrated │
