AME5130 is a micro power step-up DC/DC converter from AME company, suitable for LCD panels requiring low current and high efficiency as well as LED applications for cellular phone back-lighting, PDAS and other hand-held devices.
The AME5130 is a fixed off‑time step‑up DC/DC converter designed for low‑current LCD bias and LED back‑lighting in handheld devices. It operates from 2 V to 5.5 V input and can drive up to eight white LEDs, with an adjustable output voltage up to 20 V.
The device features a 400 ns switch‑off time, internal 0.7 µA switch, and shutdown current of 0.01 A. It is supplied in a small 5‑lead SOT‑25 package and supports a wide temperature range of –40 °C to +85 °C. Detailed pin descriptions, electrical specifications, and layout recommendations are provided for optimal performance.
