General Description
The MAX5058/MAX5059 enable secondary-side syn-
chronous rectification in isolated power supplies using
widely available power MOSFETs. These devices facili-
tate the commutation of the secondary-side MOSFETs by
providing a clean gate-drive signal that is synchronized
to the power MOSFET switching in the primary side of
the isolation transformer. The MAX5058/MAX5059 com-
plement the MAX5051 and MAX5042/MAX5043 primary-
side PWM ICs and enable the design of high-efficiency
synchronously rectified isolated power supplies.
Simultaneous conduction of the primary side and the
freewheeling synchronous rectifier MOSFET is avoided
by having a look-ahead signal (before the primary-side
MOSFETs turn ON), thus eliminating large current spikes
resulting from a shorted transformer secondary.
An on-board error amplifier with a versatile current ref-
erence output enables virtually unlimited possibilities in
reference-voltage generation. Reference voltage for the
error amplifier is generated by connecting an appropri-
ate resistor to this output.
Low on-resistance margining MOSFETs integrated on-
chip allow for implementation of a margining circuit
without the use of external switches. The MAX5058 pro-
vides a 5V LDO output for logic-level MOSFETs while
the MAX5059 provides a 10V LDO output for conven-
tional 10V MOSFETs.
The MAX5058/MAX5059 are designed to enable paral-
leling of multiple power supplies for accurate current
sharing using a simple 2-wire, differential, current-share
bus. Parallelability enables expansion of the power
capabilities and simplifies thermal management in high-
output-current applications. When used in conjunction
with the MAX5051, the primaries can also be synchro-
nized and operated 180 degrees out of phase.
The MAX5058/MAX5059 are available in a 28-pin ther-
mally enhanced TSSOP package and operate over a
wide -40°C to +125°C temperature range.
