GENERAL DESCRIPTION

The ADP1614ACPZ-1.3-R7 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 ADP1614ACPZ-1.3-R7 is available with a pin-adjustable current limit that is set via an external resistor with the boost switching frequency fixed to either 650 kHz or 1.3 MHz

Alternatively, the ADP1614ACPZ-1.3-R7 is also available with fixed 3 A current limit and a pin-selectable frequency. With a package height of 0.8 mm, the ADP1614ACPZ-1.3-R7 is optimal for space constrained applications, such as portable devices or thin film transistor (TFT) liquid crystal displays (LCDs).

The ADP1614ACPZ-1.3-R7 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 ADP1614ACPZ-1.3-R7 is available in a Pb-free, 10-lead lead frame chip scale package (LFCSP).
