This becomes of great consideration for input voltage at 12V or below. In order to enable proper operation of the converter, in particular during load transients, an additional input capacitor is required. Minimum required input capacitance, mounted close to the input pins, is 1000µF with ESR < 0.1 Ω. Since inductance of the input power cables could have significant voltage drop due to rate of change of input current di(in)/dt during transient load operation an external capacitance on the output of the converter is required to reduce di(in)/dt. It is required to use at least 470 µF (ESR < 0.07Ω) on the output. Another constraint is minimum rms current rating of the input and output capacitors which is application dependent. One component of input rms current handled by input capacitor is high frequency component at switching frequency of the converter (typ. 400kHz) and is specified under “Input terminal ripple current” ic. Typical values at full rated load and 24 Vin are provided in Section “Characteristic Waveforms” for each model and are in range of 0.56A - 0.6A. Second component of the ripple current is due to reflected step load current on the input of the converter. Similar consideration needs to be taken into account for output capacitor and in particular step load ripple current component. Consult the factory for further application guidelines. Additionally, for EMI conducted measurement it is necessary to use 5µH LISNs instead of typical 50µH LISNs. The negative logic version turns on when the ON/OFF pin is at logic low and turns off when at logic high. The converter is on when the ON/OFF pin is either shorted to -INPUT pin or kept below 0.8V. The converter is off when the ON/OFF pin is either left open or external voltage greater than 2V and not more than 12V is applied between ON/OFF pin and -INPUT pin. See the Electrical Specifications for logic high/low definitions. The ON/OFF pin is internally pulled up to typically 4.5V via resistor and connected to internal logic circuit via RC circuit in order to filter out noise that may occur on the ON/OFF pin. A properly de-bounced mechanical switch, open-collector transistor, or FET can be used to drive the input of the ON/OFF pin. The device must be capable of sinking up to 0.36mA at a low level voltage of < 0.8V. During logic high, the typical maximum voltage at ON/OFF pin (generated by the converter) is 4.5V, and the maximum allowable leakage current is 160µA. If not using the remote on/off feature leave the ON/OFF pin open. TTL Logic Level - The range between 0.81V as maximum turn off voltage and 2V as minimum turn on voltage is considered the dead-band. Operation in the dead-band is not recommended. External voltage for ON/OFF control should not be applied when there is no input power voltage applied to the converter. Protection Features: ON/OFF (Pin 3) Input Undervoltage lockout (UVLO) The ON/OFF pin is used to turn the power converter on or off remotely via a system signal and has positive logic. A typical connection for remote ON/OFF function is shown in Fig. 1. Input undervoltage lockout is standard with this converter. The converter will shut down when the input voltage drops below a pre-determined voltage. The input voltage must be typically above 8.5V for the converter to turn on. Once the converter has been turned on, it will shut off when the input voltage drops typically below 8V. If the converter is started by input voltage (ON/OFF (pin 3) left open) there is typically 500msec delay from the moment when input voltage is above 8.5V turn-on voltage and the time when output voltage starts rising. This delay is intentionally provided to prevent potential startup issues especially at low input voltages. Vin (+) ICH CONVERTER Vout (+) (TOP VIEW) Rload ON/OFF Vin CONTROL INPUT Vin (-) Vout (-) Fig. 1: Circuit configuration for ON/OFF function. The positive logic version turns on when the ON/OFF pin is at logic high and turns off when at logic low. The converter is on when the ON/OFF pin is either left open, or external voltage not more than 12V is applied between ON/OFF pin and -INPUT pin. See the Electrical Specifications for logic high/low definitions. Output Overcurrent Protection (OCP) The converter is protected against overcurrent or short circuit conditions. Upon sensing an overcurrent condition, the converter will switch to constant current operation and thereby begin to reduce output voltage. When the output voltage drops below approx. 75% of the nominal value of output voltage, the converter will shut down. Once the converter has shut down, it will attempt to restart nominally every 500msec with a typical 3% duty cycle. The attempted restart will continue indefinitely until the overload or short circuit conditions are removed or the output voltage rises above 75% of its nominal value. www.murata-ps.com/support MDC_ICH_360W_A05 Page 7 of 17 ICH 360-Watt Series Wide Input Isolated Half Brick DC-DC Once the output current is brought back into its specified range, the converter automatically exits the hiccup mode and continues normal operation. During initial startup, if output voltage does not exceed typical 75% of nominal output voltage within 20 msec after the converter is enabled, the converter will be shut down and will attempt to restart after 500 msec. Output Overvoltage Protection (OVP) The converter will shut down if the output voltage across Vout (+) (Pin 5) and Vout (-) (Pin 9) exceeds the threshold of the OVP circuitry. The OVP circuitry contains its own reference, independent of the output voltage regulation loop. Once the converter has shut down, it will attempt to restart every 500 msec until the OVP condition is removed. Overtemperature Protection (OTP) The ICH converters have non-latching overtemperature protection. It will shut down and disable the output if temperature at the center of the base plate exceeds a threshold of 114ºC (typical). The converter will automatically restart when the base temperature has decreased by approximately 20ºC Safety Requirements Basic Insulation is provided between input and the output. Output Voltage Adjust/TRIM (pin7) The TRIM pin allows user to adjust output voltage 10% up or down relative to rated nominal voltage by addition of external trim resistor. Due to absence of Remote Sense Pins, an external trim resistor should be connected to output pins using Kelvin connection. If trimming is not used, the TRIM pin should be left open. Trim Down - Decrease Output Voltage Trimming down is accomplished by connecting an external resistor, Rtrim-down, between the TRIM (pin7) and the Vout(-) (pin 9) using Kelvin connection, with a value of: R trim-d own = ( 3010 a) 50A for 9V < Vin
