Output Voltage Adjustment
Output voltage trim allows the user to increase or decrease the output voltage set point of a module. This is
accomplished by connecting an external resistor between the TRIM pin and either the VO(+) or VO(–) pins. With an
external resistor between the TRIM and VO(+) pins (Radj-down), the output voltage set point (VO, adj) decreases. With
an external resistor between the TRIM pin and VO(–) pin (Radj-up), VO, adj increases.
The following equations determine the required external resistor value to obtain an output voltage change of %:
The adjusted output voltage cannot exceed 110% of the nominal output voltage between the VO(+) and VO(–) ter-
minal.
The modules have a fixed current-limit set point. Therefore, as the output voltage is adjusted down, the available
output power is reduced. In addition, the minimum output current is a function of the output voltage. As the output
voltage is adjusted down, the minimum required output current can increase.
Output Overvoltage Protection
The output overvoltage clamp consists of control circuitry, independent of the primary regulation loop, that monitors
the voltage on the output terminals. The control loop of the protection circuit has a higher voltage set point than the
primary loop (see Feature Specifications table). In a fault condition, the overvoltage clamp ensures that the output
voltage does not exceed VO, clamp, max. This provides a redundant voltage-control that reduces the risk of output
overvoltage.
