General Description
The MAX856–MAX859 are high-efficiency, CMOS, step-up, 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).
The MAX856–MAX859 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/MAX857 have a 500mA peak inductor current limit. The MAX858/MAX859
have a 125mA peak inductor current limit.
