Be aware of this limit in applications where the VTM is being driven above its nominal output voltage. If less than 26 Vdc is present at the +In and -In ports, a continuous VC voltage must be applied for the VTM to process power. Otherwise VC voltage need only be applied for 10 ms after the voltage at the +In and -In ports has reached or exceeded 26 Vdc. If the input voltage exceeds the overvoltage turn-off, the VTM will shutdown. The VTM does not have internal input reverse polarity protection. Adding a properly sized diode in series with the positive input or a fused reverse-shunt diode will provide reverse polarity protection. TM – For Factory Use Only VC – VTM Control The VC port is multiplexed. It receives the initial VCC voltage from an upstream PRM, synchronizing the output rise of the VTM with the output rise of the PRM. Additionally, the VC port provides feedback to the PRM to compensate for the VTM output resistance. In typical applications using VTMs powered from PRMs, the PRM’s VC port should be connected to the VTM VC port. In applications where a VTM is being used without a PRM, 14 V must be supplied to the VC port for as long as the input voltage is below 26 V and for 10 ms after the input voltage has reached or exceeded 26 V. The VTM is not designed for extended operation below 26 V. The VC port should only be used to provide VCC voltage to the VTM during startup. PC – Primary Control The Primary Control (PC) port is a multifunction port for controlling the VTM as follows: Disable – If PC is left floating, the VTM output is enabled. To disable the output, the PC port must be pulled lower than 2.4 V, referenced to -In. Optocouplers, open collector transistors or relays can be used to control the PC port. Once disabled, 14 V must be re-applied to the VC port to restart the VTM. Primary Auxiliary Supply – The PC port can source up to 2.4 mA at 5 Vdc. +Out / -Out DC Voltage Output Ports The output and output return are through two sets of contact locations. The respective +Out and –Out groups must be connected in parallel with as low an interconnect resistance as possible. To take full advantage of the VTM, the user should note the low output impedance of the device. The low output impedance provides fast transient response without the need for bulk POL capacitance. Limited- life electrolytic capacitors required with conventional converters can be reduced or even eliminated, saving cost and valuable board real estate. -In PC VC TM +In -Out +Out -Out +Out Bottom View A B C D E F G H J K L M N P R T 4 3 2 1 A B C D E H J K L M N P R T Figure 9 — VTM pin configuration Signal Name Pin Designation +In A1-E1, A2-E2 –In L1-T1, L2-T2 TM H1, H2 VC J1, J2 PC K1, K2 +Out A3-D3, A4-D4, J3-M3, J4-M4 –Out E3-H3, E4-H4, N3-T3, N4-T4 |
