GENERAL DESCRIPTION
The ADP1614 is a step-up, dc-to-dc switching converter with an integrated power switch capable of providing an output voltage as high as 20 V. The ADP1614 is available with a pin adjustable current limit that is set via an external resistor. The boost switching frequency is fixed to either 650 kHz or 1.3 MHz.
With a package height of 0.8 mm, the ADP1614 is optimal for space constrained applications, such as portable devices or thin film transistor (TFT) liquid crystal displays (LCDs).
