5V or Adjustable, Low-Voltage,
Step-Up DC-DC Controller
_______________General Description
The MAX608 low-voltage step-up controller operates
from a 1.8V to 16.5V input voltage range. Pulse-fre-
quency-modulation (PFM) control provides high effi-
ciency at heavy loads, while using only 85μA (typical)
when operating with no load. In addition, a logic-con-
trolled shutdown mode reduces supply current to 2μA
typical. The output voltage is factory-set at 5V or can be
adjusted from 3V to 16.5V with an external resistor
divider.
The MAX608 is ideal for two- and three-cell battery-
powered systems. An operating frequency of up to
300kHz allows use with small surface-mount compo-
nents.
The MAX608 operates in “bootstrapped” mode only
(with the chip supply, OUT, connected to the DC-DC
output). For a 12V output without external resistors, or
for nonbootstrapped applications (chip supply connect-
ed to input voltage), refer to the pin-compatible
MAX1771. The MAX608 is available in 8-pin DIP and
SO packages.
