This document is about the technical data of ADP1612. ADP1612 is a step-up dc-to-dc switching converter with an integrated 1.5 A, 0.15 Ω power switch capable of providing an output voltage as high as 20 V. It is suitable for space-constrained applications such as portable devices or thin film transistor (TFT) liquid crystal displays (LCDs).
The ADP1612 step‑up switching converter operates from 1.8 V to 6 V input and can deliver up to 20 V output. It features a fully integrated 1.5 A power switch, selectable 600 kHz or 1.25 MHz PWM frequency, adjustable soft‑start, UVLO, and thermal shutdown. The device is offered in a lead‑free 8‑lead MSOP package and is suited for space‑constrained applications such as portable devices and TFT‑LCD bias supplies.
The datasheet provides detailed specifications, pin descriptions, typical performance curves, layout guidelines, and ordering information. It also explains the current‑mode PWM control scheme, frequency selection method, and shutdown behavior, helping designers implement the converter efficiently in their circuits.
