The MAX15005A evaluation kit (EV kit) is a fully assembled
and tested PCB that contains an 11W flyback DC-DC
converter for vacuum-fluorescent displays (VFDs) in
automotive applications. The circuit uses a MAX15005A
high-performance, current-mode pulse-width modulation
(PWM) controller in a 16-pin TSSOP package. The EV kit
circuit is configured for output voltages of 3V, 60V, and
110V, and provides up to 650mA, 12mA, and 55mA of
current from the respective output. Additionally, a 5V low-dropout
(LDO) voltage regulator output is provided that
can source up to 15mA. Power for the EV kit circuit is provided
from a 6.5V to 16V DC source. The MAX15005A EV
kit input circuit can sustain a 40V transient.
High efficiency of up to 71% is achieved using a single-transistor
flyback DC-DC converter topology. Low cost
is achieved through the use of direct secondary-side
regulation that does not require optical couplers. Input
undervoltage lockout (UVLO), output overvoltage protection
(OVP), and soft-start provide for a robust 11W
power supply.
Operation at 100kHz minimizes the size of the transformer
and passive components.
Warning: The MAX15005A EV kit is designed to operate
with high voltages. Dangerous voltages are present on
this EV kit and on equipment connected to it. Users who
power up this EV kit, or power the sources connected to
it, must be careful to follow safety procedures appropriate
to working with high-voltage electrical equipment.
Under severe fault or failure conditions, this EV kit may
dissipate large amounts of power, which could result in
the mechanical ejection of a component or of component
debris at high velocity. Operate this kit with care to
avoid possible personal injury.
