Digital Camera Step-Up Slave
DC-DC Controller
General Description
The MAX1801 step-up slave DC-DC controller is used
with either the MAX1800 (step-up) or the MAX1802 (step-
down) master DC-DC converter to provide a complete
power-supply solution for digital still and digital video
cameras. By using the master converter’s reference volt-
age and oscillator, the size and the cost of the slave con-
troller are reduced and all converters are guaranteed to
switch at the same frequency.
The MAX1801 drives an external N-channel MOSFET
and can be used in step-up, single-ended primary
inductance converter (SEPIC), and flyback topologies. If
extra supplies are required for a new design, slave con-
trollers can be added to an existing master circuit with
minimal redesign, saving both cost and time. The
MAX1801 features a built-in soft-start, short-circuit pro-
tection, and an adjustable duty-cycle limit.
Features
o Provides Simple Expandability for the MAX1800
and MAX1802 Master Converters
o Operates in Step-Up, SEPIC, and Flyback
Topologies
o 100kHz to 1MHz Adjustable Operating Frequency
o Duty-Cycle Limit Adjustable from 40% to 90%
o Soft-Start
o Short-Circuit Protection
o 0.01μA Supply Current in Shutdown Mode
o Tiny 8-Pin SOT23 Package
