MAX856CSA+ - DC-DC Switching Boost

MAX856CSA+ - DC-DC Switching Boost (Step Up) Regulator


The MAX856CSA+ is a high-efficiency, CMOS, Step-up DC-DC Switching Regulator for small, low input voltage or battery-powered systems. The MAX856 accepts a positive input voltage between 0.8V and VOUT and convert it to a higher, pin-selectable output voltage of 3.3V or 5V. Typical efficiencies are greater than 85%. Typical quiescent supply current is 25µA (1µA in shutdown). The MAX856 combine ultra-low quiescent supply current and high efficiency to give maximum battery life. An internal MOSFET power transistor permits high switching frequencies. This benefit, combined with internally set peak inductor current limits, permits the use of small, low-cost inductors. The MAX856 have a 500mA peak inductor current limit.
