Input/Output (I/O) Connector Description

VIN – Terminal on J2— is the power input terminal for the converter. The terminal edge connector also

provides a power (VIN) and ground (GND) connection to allow the user to attach the EVM to a

cable harness.

VOUT – Terminal on J3— is the regulated output voltage for the converter. The terminal edge connector

also provides a power (VOUT) and ground (GND) connection to allow the user to attach the EVM to

a cable harness.

GND – Terminal on J2 and J3— are the ground reference for the converter. The terminal edge connector

also provides a GND connection for attaching the EVM to a cable harness.

EN – Testpoint— is used to enable the converter by supplying a voltage greater than 2.2 V (typ) or just to

monitor the voltage on this terminal whenever a resistor divider is in place (for precision enable

applications). The LM46000EVM is built for a precision enable application with resistors RENT and

RENB pre-assembled. The regulator will be enabled when VIN > 3.5 V. This threshold can be

calculated by:
