ADP1613ARMZ-R7
Overview
The ADP1613ARMZ-R7 is a high-efficiency boost regulator designed to operate from input voltages as low as 2.5V, making it suitable for single-cell Li-ion and energy-harvesting power sources. It features a high 2A internal switch and selectable switching frequencies of 650kHz or 1.3MHz to optimize for either high efficiency or small external component size. The device can provide adjustable output voltages up to 20V, providing flexibility for various step-up and SEPIC configurations.
Why Choose This Part
The part offers a high power density by integrating a 2.5A switch into a compact 8-MSOP package. Its dual-frequency operation allows engineers to minimize inductor size at 1.3MHz or maximize efficiency at 650kHz. With a low 2uA shutdown current, it significantly extends battery life in standby-heavy applications.
Applications
Key Specifications
Getting Started
Designers should select the switching frequency by tying the FREQ pin to GND (650kHz) or VIN (1.3MHz). Ensure that the compensation network on the COMP pin is tuned for the specific inductor and output capacitor values to maintain loop stability. Analog Devices provides the ADIsimPower tool to assist in calculating component values for specific VOUT and IOUT requirements.
