lockout

• UL Safety Agency Approval

(UVLO), a differential remote sense, and an industry

standard output voltage adjustment using an external

resistor.

Protection

features

include

output

overcurrent protection (OCP), overvoltage protection

(OVP), and thermal shutdown (OTP).

The modules are fully integrated for stand-alone

operation, and require no additional components.
