DS_ DCM04S0A0S12PFA_10022013 E-mail: DCDC@delta.com.tw http://www.deltaww.com/dcdc P10 FEATURE DESCRIPTIONS (CON.) For proper voltage sequencing, first, input voltage is applied to the module. The On/Off pin of the module is left unconnected (or tied to GND for negative logic modules or tied to VIN for positive logic modules) so that the module is ON by default. After applying input voltage to the module, a minimum 10msec delay is required before applying voltage on the SEQ pin. This delay gives the module enough time to complete its internal power-up soft-start cycle. During the delay time, the SEQ pin should be held close to ground (nominally 50mV ± 20 mV). This is required to keep the internal op-amp out of saturation thus preventing output overshoot during the start of the sequencing ramp. By selecting resistor R1 (see Figure. 34) according to the following equation 05.0
249501 VinR
The voltage at the sequencing pin will be 50mV when the sequencing signal is at zero. After the 10msec delay, an analog voltage is applied to the SEQ pin and the output voltage of the module will track this voltage on a one-to-one volt bases until the output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their set-point voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. When using the EZ-SEQUENCETM feature to control start-up of the module, pre-bias immunity during startup is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during start-up. When using the EZ-SEQUENCETM feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. Figure 34: Circuit showing connection of the sequencing signal to the SEQ pin. Simultaneous Simultaneous tracking (Figure 35) is implemented by using the TRACK pin. The objective is to minimize the voltage difference between the power supply outputs during power up and down. The simu ltaneous tracking can be accomplished by connecting VoPS1 to the TRACK pin of PS2. Please note the voltage apply to TRACK pin needs to always higher than the VoPS2 set point voltage.
