Detailed Description
Table 3. Component Suppliers
The remainder of this document contains the detailed
information you’ll need to design a circuit that differs
from the two Standard Application Circuits. If you are
using one of the predesigned circuits, the following
sections are purely informational.
The MAX606/MAX607 CMOS, step-up DC-DC convert-
ers employ a current-limited pulse-frequency control
scheme. This control scheme regulates a boost topolo-
gy to convert input voltages between 3V and 5.5V into

either a pin-programmable 5V/12V output, or an
adjustable output between V IN and 12.5V. It optimizes
performance over all input and output voltages, and
guarantees output accuracy to ±4%.
The ultra-high switching frequency (typically 1MHz for
the MAX606 and 0.5MHz for the MAX607) permits the
use of extremely small external components, making
these converters ideal for use in Types 1, 2, and 3 flash
memory and PCMCIA applications.
Pulse-Frequency-Modulation
Control Scheme
The MAX606/MAX607 employ a proprietary, current-
limited control scheme that combines the ultra-low sup-
ply current of traditional pulse-skipping converters with
the high full-load efficiency of current-mode pulse-
width-modulation converters. This particular control
scheme is similar to the one used in previous current-
limited devices (which governed the switching current
via maximum on-time, minimum off-time, and current
limit), except it varies the on and off times according to
the input and output voltages. This important feature
enables the MAX606/MAX607 to achieve ultra-high
switching frequencies while maintaining high output
accuracy, low output ripple, and high efficiency over a
wide range of loads and input/output voltages.
Figure 3 shows the functional diagram of the MAX606/
MAX607. The internal power MOSFET is turned on when
the error comparator senses that the output is out of reg-
ulation. The power switch stays on until either the timing
circuit turns it off at the end of the on-time, or the switch
current reaches the current limit. Once off, the switch
remains off during the off-time. Subsequently, if the out-
put is still out of regulation, another switching cycle is ini-
tiated. Otherwise, the switch remains turned off as long
as the output is in regulation.
