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).

The ADP1614 operates in current-mode pulse-width modulation

(PWM) with up to 94% efficiency. Adjustable soft start prevents

inrush currents when the part is enabled. The PWM current-mode

architecture allows excellent transient response, easy noise filtering,

and the use of small, cost-saving external inductors and capacitors.

Other key features include undervoltage lockout (UVLO), thermal

shutdown (TSD), and logic controlled enable.

The ADP1614 is available in a Pb-free, 10-lead lead frame chip

scale package (LFCSP).
