(2) never connect capacitors from vo adjust to either + sense, gnd, or vo. any capacitance added to the vo adjust pin affects the stabilit y of the regulator. (3) for output voltages less than 1.2 v, the output ripple may increase (up to 2 ) when operating at input voltages greater than (vo 12). adjusting the switching frequency using the smartsync feature may increase or decrease this ratio. parallel operation the pmr 8210 module is capable of being configured in parallel with another pmr 8210 module to share load current. to parallel the two modules, it is necessary to configure one module as the master and one module as the slave. to configure a module as the ma ster, connect the config pin (pin 1) to gnd. the config pin of the slave must be connected to v i . in order to share current, pins 2 through 5 of both the master and slave mu st be connected between the two modules. the module that is configured as the master is used to control all of the functions of the two modules including inhibit, on/off control, autotrack sequencing, turbotrans, smartsync, +/- remote sense, and output voltage adjust. the master and the slave must be powered from the same input voltage supply. when using turbotrans while paralleling two modules, the turbotrans resistor, r tt , must be connected from the turbotrans pin (pin 19) of the master module to the +sense pin (pin 17) of the master module. when paralleling modules the procedure to calculate the proper value of output capacitance and r tt is similar to that explained in the turbotrans selection section, however the values must be calculated for a single module. therefore, the total output current load step must be ha lved before determining the required output capacitance and the r tt value as explained in the turbotrans selection section. the value of output capacitance calculated is the minimum required output capacitance per module and the value of rtt must be calculated using this value of output capacitance. the turbotrans pin of the slave module must be left open. current sharing layout in current sharing applications the v i pins of both modules must be connected to the same input bus. the v o pins of both modules are connected toget her to power the load. the gnd pins of both modules are connected via the gnd plane. four other inter-connection pins are connected between the modules. below figure shows the required layout of the inter- connection pins for two modules configured to share current. notice that the share (pin 2) connection is routed between the comp (pin 3) and clkio (pin 5) connections. agnd (pin 4) should be connected as a thic ker trace on an adjacent layer, running parallel to pins 2, 3 and 5. agnd must not be connected to the gnd plane. remote sense the products have remote sense that can be used to compensate for voltage drops between the output and the point of load. the sense traces should be located close to the pcb ground layer to reduce noise susceptibility. the remote sense circuitry will compensate for up to 0.3 voltage drop between output pins and the point of load. if the remote sense is not needed +sense should be connected to +out and ?sense should be connected to ?out. over temperature protection (otp) the regulators are protected fr om thermal overload by an internal over temperature shutdown circuit. if the internal temperature exceeds the otp threshold, the module?s inhibit control is internally pulled low. this turns the output off. the voltage drops as the external output capacitors are discharged by the load circuit. the product will make continuous attempts to start up (non-latching mode) and resume normal operation automatically when the temper ature has dropped >10c below the temperature threshold. e pmr 8000 series pol regulator input 8 - 14 v, output up to 40 a / 210 w en/lzt 146 411 r1b november 2009 ? ericsson ab technical speci?cation 11

function auto-track was designed to simplify the amount of circuitry required to make the output voltage from each unit power up and power down in sequence. the sequencing of two or more supply voltages during power up is a common requirement for complex mixed-signal applications, that use dual-voltage vlsi ics such as dsps, micro-processors and asics. notes on use of auto-track? 1. the track pin voltage must be allowed to rise above the module set-point voltage before the module regulates at its adjusted set-point voltage. 2. the auto-track function tracks almost any voltage ramp during power up, and is compatible with ramp speeds of up to 1 v/ms. 3. the absolute maximum voltage that may be applied to the track pin is the input voltage v i . 4. the module cannot follow a voltage at its track control input until it has completed it s soft-start initialization. this takes about 20 ms from the time that a valid voltage has been applied to its input. during this period, it is recommended that the track pin be held at ground potential. 5. the auto-track function is disabled by connecting the track pin to the input voltage (v i ). when auto-track is disabled, the output voltage rises according to its softstart rate after input power has been applied. 6. the auto-track pin should never be used to regulate the module?s output voltage fo r long-term, steady-state operation. smart sync smart sync is a feature that allows multiple power modules to be synchronized to a common frequency. when not used, this pin must be connect to gnd. driving the smart sync pins with an external oscillator set to the desired frequency, synchronizes all connected modules to the selected requency. the synchronization frequency can be higher or lower than the nominal switching frequency of the modules within the range of 240 khz to 400 khz. synchronizing modules powered from the same bus eliminates beat frequencies reflected back to the input supply, and also reduces emi filtering requirements. eliminating the low beat frequencies (usually<10khz) allows the emi filter to be designed to attenuate only the synchronization frequency. power modules can also be synchronized out of phase to minimize ripple current and reduce input capacitance requirements. the pmr 8210 requires that t he external synchronization frequency be present before a valid input voltage is present or before release of the inhibit control. pre-bias startup capability a prebias startup condition occurs as a result of an external voltage being present at the out put of a power module prior to its output becoming active.this often occurs in complex digital systems when current from another power source is backfed through a dual-supply logic component, such as fpga or asic. the pmr family of regulators incorporate synchronous rectifiers, but will not sink curr ent during startup, or whenever the inhibit pin is held low. however, to ensure satisfactory operation of this function, certain conditions must be maintained. for more inforamtion, please refer to application note 205. turbo trans tm technology turbo trans tm optimizes the transi ent response of the regulator with added external capacitance using a single external resistor. the benefits of this technology include: reduced output capacitance, minimized output voltage deviation following a load transient, and enhanced stability when using ultra-low esr output capacitors. the amout of output capacitance required to meet a target output voltage deviation, is reduded with turbo trans tm activated. likewise, for a given amout of output capacitance, with turbo trans tm engaged, the amplitude of the voltage deviation following a load transient is reduced. applic ations requiring tight transient voltage tolerances and minimized capacitor footprint area benefit from this technology. utilizing turbo trans tm requires connecting a resistor, r tt , between the +sense pin (pin 17) and the turbo trans tm pin (pin 19), the value of the resistor directly corresponds to the amount of output capacitance required. for the pmr 8210, the minimum required capacitance is 1000f. when using turbo trans tm , capacitors with a capacitanceesr product below 10,000 fm ?
