Maxim MAX17598ATE+T

任意一种8V ~ 29V

Overview

The MAX17598ATE+ is a buck/boost regulating charge pump that generates a regulated output voltage from a single lithium-ion (Li+) cell, or two or three NiMH or alkaline cells for small hand-held portable equipment. The MAX17598ATE+ operates over a wide +1.6V to +5.5V input voltage range and generates a fixed 3.3V or adjustable (2.5V to 5.5V) output (Dual Mode). Maxim's unique charge-pump architecture allows the input voltage to be higher or lower than the regulated output voltage. Despite its high 1.5MHz operating frequency, the MAX17598ATE+ maintains low 50μA quiescent supply current. Designed to be an extremely compact buck/boost converter, this device requires only three small ceramic capacitors to build a complete DC-DC converter capable of generating a guaranteed 100mA (min) output current from a +2.5V input. For added flexibility, the MAX17598ATE+ also includes an open-drain power-OK (POK) output that signals when the output voltage is in regulation. The MAX17598ATE+ is available in a space-saving 10-pin μMAX package that is 1.09mm high and half the size of an 8-pin SO.
