Current-Mode PWM Controllers with Integrated
Startup Circuit for Isolated Power Supplies
General Description
The MAX5014/MAX5015 integrate all the building
blocks necessary for implementing DC-DC fixed-fre-
quency isolated power supplies. These devices are
current-mode controllers with an integrated high-volt-
age startup circuit suitable for isolated telecom/industri-
al voltage range power supplies. Current-mode control
with leading-edge blanking simplifies control-loop
design and internal ramp compensation circuitry stabi-
lizes the current loop when operating at duty cycles
above 50% (MAX5014). The MAX5014 allows 85%
operating duty cycle and could be used to implement
flyback converters, whereas the MAX5015 limits the
operating duty cycle to less than 50% and can be used
in single-ended forward converters. A high-voltage
startup circuit allows these devices to draw power
directly from the 18V to 110V input supply during start-
up. The switching frequency is internally trimmed to
275kHz 鹵10%, thus reducing magnetics and filter com-
ponent costs.
The MAX5014/MAX5015 are available in 8-pin SO
packages. An evaluation kit (MAX5015EVKIT) is also
available.
Warning:
The MAX5014/MAX5015 are designed to
operate with high voltages. Exercise caution.
