7 / 46 page Ericsson Internal PRODUCT SPECIFICATION 4 (5) Prepared (also subject responsible if other) No. ESECZHW 2/1301-BMR 636 01/E4 Uen Approved Checked Date Rev Reference SEC/D (Betty Wu) EZYPING 2009-8-5 A 1.0 V/30 A Typical Characteristics PKB 4318N PINB Start-up Shut-down Start-up enabled by connecting V I at: T ref = +25°C, VI = 53 V, I O = 30 A resistive load. Top trace: output voltage (0.5 V/div.). Bottom trace: input voltage (50 V/div.). Time scale: (5 ms/div.). Shut-down enabled by disconnecting V I at: T ref = +25°C, VI = 53 V, I O = 30 A resistive load. Top trace: output voltage (0.5 V/div.). Bottom trace: input voltage (50 V/div.). Time scale: (0.5 ms/div.). Output Ripple & Noise Output Load Transient Response Output voltage ripple at: T ref = +25°C, VI = 53 V, I O = 30 A resistive load. Trace: output voltage (20 mV/div.). Time scale: (2 μs/div.). Output voltage response to load current step- change (7.5-22.5-7.5 A) at: T ref =+25°C, VI = 53 V. Top trace: output voltage (100 mV/div.). Bottom trace: load current (30 A/div.). Time scale: (0.1 ms/div.). Output Voltage Adjust (see operating information) Passive adjust The resistor value for an adjusted output voltage is calculated by using the following equations: For a desired change of the nominal output voltage, the value of the resistor should be ) ( 1 Ω − − = k V V V Radj adj oi adj Where adj V is adjusted output voltage, and oi V is initial output voltage. Vertical bars indicate absolute value. E PKB 4000 series DC/DC converters, Input 36-75 V, Output 30 A/90 W EN/LZT 146 394 R5D October 2013 © Ericsson AB Technical Specification 7 |
