● Proven PCB Layout

The EV kits are conﬁgured to demonstrate the optimum

performance and component size. The EV kits pro-

vide provisions for enable/disable settings and selecting

the modes of operation (pulse-width modulation/pulse-

frequency modulation/discontinuous-conduction mode

[PWM/PFM/DCM]). The EV kits feature programmable

input undervoltage-lockout (UVLO), adjustable soft-start,

open-drain RESET signal, and external clock synchroni-

zation. The EV kits also provide a good layout example,

which is optimized for conducted, radiated EMI, and ther-

mal performance. For more details, refer to the Beneﬁts

and Features section in the MAX17644 IC data sheet.

● Fully Assembled and Tested

● Complies with CISPR32 (EN55032) Class B
