The term “push-pull” refers to two charge pumps working in parallel and in opposing phase to deliver charge to support the output voltage. When one capacitor is pumping charge to the output, the other is recharging. This technique minimizes voltage loss and output voltage ripple. The converter accommodates input voltages from +3 V to +3.6 V and can provide 320 mA using 2.2 µF MLCC pump capacitors. Converter operation can be enabled or disabled simply by an input signal. The package is enhanced with Analog Devices’ proprietary Thermal Coastline feature, which allows up to 980 mW of power dissipation at room temperature. The exceptionally thin TSSOP-16 package and the requirement of only capacitors (no inductors) to support the converter operation allows slim designs, e.g., for TFT or LCD display panels.
