to less than 650mA, 12mA, and 55mA for each respec-
tive output detailed above in step 7.
The MAX15005A EV kit is an 11W flyback DC-DC con-
verter that provides output voltages of 3V at up to
650mA, 60V at up to 12mA, and 110V at up to 55mA.
The MAX15005A flyback power supply is designed to
provide power to automotive VFDs. The circuit can be
powered from a 6.5V to 16V DC source, which provides
3A to the EV kit.
The flyback DC-DC converter achieves up to 71%
efficiency and the single-transistor topology provides
for a lower-cost design. The MAX15005A EV kit provides
cycle-by-cycle primary-side current-limit protection.
Current-sense resistor R6 senses the current through the
transformer’s (T1) primary winding, switching transistor
(N1), and turns off the transistor when the trip level of 0.3V
is reached. The MAX15005A EV kit features a resistor/
capacitor/diode (RCD) snubber network (R2, C11, and
D1) to minimize leakage energy ringing and clamp the
voltage at the drain of MOSFET N1 during switching.
Secondary-side regulation through feedback resistors
R13 and R14 provide ±3% regulation for the 110V
output (V_Anode). Resistors R8, R10, and R15 preload
the respective output and assist with overall regulation
at minimum loading. UVLO provides controlled turn-on
and shutdown during brownouts, power-up, or
power-down. The UVLO setting can be changed by
replacing resistor R18.
The MAX15005A analog soft-start allows the output volt-
age to slowly ramp up in a controlled manner within
56ms and is set by capacitor C8. The OVP is provided
by independently sensing the 110V output (V_Anode)
through resistors R11 and R12.
