FEATURES DESCRIPTIONS (CON.)

Input Under-Voltage Lockout

The input under-voltage lockout prevents the converter from being damaged while operating when the input voltage is too low. The lockout occurs between 7.7V to 8.6V.

Over-Current and Short-Circuit Protection

The NC series modules have non-latching over-current and short-circuit protection circuitry. When over current condition occurs, the module goes into the non-latching hiccup mode. When the over-current condition is removed, the module will resume normal operation.

An over current condition is detected by measuring the voltage drop across the high-side MOSFET. The voltage drop across the MOSFET is also a function of the MOSFET’s Rds(on). Rds(on) is affected by temperature, therefore ambient temperature will affect the current limit inception point.

The unit will not be damaged in an over current condition because it will be protected by the over temperature protection.

Remote Sense

Over Temperature Protection (OTP)

To provide additional over-temperature protection in a fault condition, the unit is equipped with a non-latching thermal shutdown circuit. The shutdown circuit engages when the temperature of monitored component exceeds approximately 130. The unit will cycle on and off while the fault condition exists. The unit will recover from shutdown when the cause of the over temperature condition is removed.

Over Voltage Protection (OVP)

The converter will shut down when an output over voltage is detected. Once the OVP condition is detected, the controller will stop all PWM outputs and will turn on low-side MOSFET driver to prevent any damage to load.

Current Sharing (optional)

The parallel operation of multiple converters is available with the NC30/NC40 (option code B). The converters will current share to be within +/- 10% of each other. In addition to connect the I-Share pin together for the current sharing operation, the remote sense lines of the paralleled units must be connected at the same point for proper operation. Also, units are intended to be turned on/enabled at the same time. Hot plugging is not recommended. The current sharing diagram show in Figure 30.

The NC30/NC40 provide Vo remote sensing to achieve proper regulation at the load points and reduce effects of distribution losses on output line. In the event of an open remote sense line, the module shall maintain local sense regulation through an internal resistor. The module shall correct for a total of 0.4V of loss. The remote sense connects as shown in Figures 29.
