MAX8546EUB-T - Brand New Maxim Integrated IC Chips
-
Description
The MAX8546EUB-T is a high-efficiency, CMOS, step-up, DC-DC switching regulator designed for small, low input voltage or battery-powered systems. It accepts a positive input voltage between 0.8V and VOUT and converts it to a higher, pin-selectable output voltage of 3.3V or 5V. The MAX8546EUB-T combines ultra-low quiescent supply current and high efficiency to maximize battery life. It is equipped with an internal MOSFET power transistor, allowing for high switching frequencies. This, along with internally set peak inductor current limits, enables the usage of small, low-cost inductors. The MAX8546EUB-T is available in 8-pin SO and µMAX packages.
