MAX857 - Step-Up DC-DC Converters

Download the MAX857 datasheet PDF. This datasheet also covers the MAX856 variant, as both devices belong to the same step-up dc-dc converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX856

MAX859 are high-efficiency, CMOS, stepup, DC-DC switching regulators for small, low input voltage or battery-powered systems.

The MAX856/MAX858 accept a positive input voltage between 0.8V and VOUT and convert it to a higher, pin-selectable output voltage of 3.3V or 5V.

19-0211; Rev 4; 5/96 EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL 3.3V/5V or Adjustable-Output, Step-Up DC-DC Converters MAX856–MAX859 _______________General Description The MAX856–MAX859 are high-efficiency, CMOS, stepup, DC-DC switching regulators for small, low input voltage or battery-powered systems. The MAX856/MAX858 accept a positive input voltage between 0.8V and VOUT and convert it to a higher, pin-selectable output voltage of 3.3V or 5V. The MAX857/MAX859 adjustable versions accept 0.8V to 6.0V input voltages and generate higher adjustable output voltages in the 2.7V to 6.0V range. Typical efficiencies are greater than 85%. Typical quiescent supply current is 25µA (1µA in shutdown).
