General Description
The MAX5003 high-voltage switching power-supply
controller has all the features and building blocks need-
ed for a cost-effective flyback and forward voltage-
mode control converter. This device can be used to
design both isolated and nonisolated power supplies
with multiple output voltages that operate from a wide
range of voltage sources. It includes a high-voltage
internal start-up circuit that operates from a wide 11V to
110V input range. The MAX5003 drives an external N-
channel power MOSFET and has a current-sense pin
that detects overcurrent conditions and turns off the
power switch when the current-limit threshold is
exceeded. The choice of external power MOSFET and
other external components determines output voltage
and power.
The MAX5003 offers some distinctive advantages: soft-
start, undervoltage lockout, external frequency synchro-
nization, and fast input voltage feed-forward. The
device is designed to operate at up to 300kHz switch-
ing frequency. This allows use of miniature magnetic
components and low-profile capacitors. Undervoltage
lockout, soft-start, switching frequency, maximum duty
cycle, and overcurrent protection limit are all adjustable
using a minimum number of external components. In
systems with multiple controllers, the MAX5003 can be
externally synchronized to operate from a common sys-
tem clock.
Warning:
The MAX5003 is designed to operate with
high voltages. Exercise caution.
The MAX5003 is available in 16-pin SO and QSOP pack-
ages. An evaluation kit (MAX5003EVKIT) is also available.
