v in , and the cur- rent limit is scaled by: v in (v in + v out ) current monitor/trimmable current limit (c option): in addition to voltage trim, the c option offers an adjustable current limit input and a current monitor output. the c option also includes an ideal diode circuit in series with the vout+ pin that prevents reverse current flow. this enables applications such as battery charging, current sharing, and current read back. vin+ vin- vin+ enable vin- vout+ vout+ i mon i mon i trim v trim vout- vout- 4 5 6 7 8 1 2 3 cout r trim-up r adjilim cin dc/dc converter figure c: current nitrtrie urrent iit setu the r trim-up resistor increases the output voltage, identical in function to the s option. the r adjitrim resistor reduces the output current limit, according to the following equation: r adjitrim = [( 0.0469 i max + i trim ) 10200 - 10 ] (?) 1.153 i max + i trim alternatively, the i trim pin can be driven from an external voltage source: v(pin5) = 2.085(i trim /i max ) + 0.0953 where i trim is the desired current limit setpoint if i limit is less than i trim , then i limit takes precedence. the i mon pin voltage tracks the output current, as shown in figure 10. this pin has a 10kohm output impedance. basic operation and features these converters use a digital controller for the buck stage and boost stage (see figure a). it automatically changes operating mode (buck mode or boost) when the line voltage or output set point changes. both stages are accomplished with synchronous rectifiers. very high efficiency is maintained over wide input and output ranges by shifting operational modes and use of synchronous rectifiers. vin+ vin- linput cin1 cin2 gate_q1 gate_q3 gate_q4 gate_q2 q1 q3 q4 q2 l loutput jumper cout1 cout2 vout+ vout- figure a: g w mode: q3, q4 are populated, jumper is open. t mode: q3, q4 are open, jumper is populated. the converter runs at a fixed frequency with a predictable emi performance. this series of quarter-brick and eighth-brick converters use the industry standard footprint and pin-out configuration. control features remote on/off: the on/off input permits the user to con- trol when the converter is on or off. only negative on/off logic is available in this power module series. negative logic on/off signal turns the module off during logic high (leave the pin floating or set voltage between 1.8~3.3 v) and turns the module on during logic low [tie to v in (-)]. output voltage trim: the output voltage can be programmed to any voltage between 0 v dc and v max by connecting one resistor between the pin 6 (trim) pin and pin 5 [sense(-)]. for a desired output voltage, the value of the resistor should be: r trim-up (v out ) = [( 11830 x v max ) _ 10912 ] ( ? ) v out + 0.058 x v max alternatively, the trim pin can be driven from an external voltage source: v(pin6) = 2.366 C 2.314 ( v out ) v max where: v out = desired output voltage v max = maximum rated output voltage to maintain the accuracy of the output voltage over load current, it is vital that any trim-up resistor be terminated directly to the converters sense(-) pin (s option) or vout(-) pin (c option), not at the connection to the load. a separate kelvin connection to the pcb pad for the vout(-) is optimal. protection features input under-voltage lockout: the converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the application note titled input system instability. the lockout circuitry is a comparator with dc hysteresis. when the input voltage is rising, it must exceed the typical turn-on voltage threshold value (listed on the specification page) before the converter will turn on. once the converter is on, the input voltage must fall below the typical turn-off voltage threshold value before the converter will turn off. output current shutdown: to provide protection in an output short condition, the unit is equipped with internal short circuit protection. when the short protection is triggered, the unit shutdowns first. after approximately 16 ms inhibit time, the units turn on again. if the short condition remains, the current limit circuit will limit the output current. the units operate normally once the fault condition is removed. internal over-voltage protection: to fully protect from excessive output voltage, the output over-voltage shutdown circuitry is contained. this ovp is independent of the trimmed set point. the shutdown point is fixed on the standard option. over-temperature shutdown: a temperature sensor on the converter senses the average temperature of the module. the thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the over-temperature shutdown value. it will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the over-temperature shutdown restart hysteresis value.
