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 with the boost switching frequency fixed to either 650 k Hz or 1.3 MHz. Alternatively, the ADP1614 is also available with fixed 3 A current limit and a pin-selectable frequency. With a package height of 0.8 mm, the ADP1614 is optimal...
