How do you regulate input voltage?
To maintain a steady voltage level regardless of the amount of current drawn from a power supply, the power supply can incorporate a voltage regulator circuit. The voltage regulator monitors the current drawn by the load and increases or decreases the voltage accordingly to keep the voltage level constant.
What is the range on input voltage for the power supply module?
Although the power system voltage is referred to as -48 V, the actual voltage varies over a range from -42 to -56 V depending on the state of charge of the batteries. The DC-DC converters themselves must operate down to a significantly lower input voltage, to allow for voltage drops within the equipment.
What is the input common mode voltage range?
INPUT COMMON MODE VOLTAGE RANGE . At the input, the CM range useful for VIN also has two rail-imposed limits, one high or close to +VS, and one low, or close to –VS. Going high, it can range from an upper CM limit of +VS – VCM(HI) as a positive maximum. For example, again using the +VS = 5 V example case, if VCM(HI)
What is the common mode voltage range for Vin?
INPUT COMMON MODE VOLTAGE RANGE. At the input, the CM range useful for VIN also has two rail-imposed limits, one high or close to +VS, and one low, or close to –VS. Going high, it can range from an upper CM limit of +VS – VCM(HI) as a positive maximum.
What is the voltage range of an op amp?
Any real op amp will have a finite voltage range of operation, at both input and output. In modern system designs, supply voltages are dropping rapidly, and 3 V to 5 V total supply voltages are now common for analog circuits such as op amps.
What happens when you decrease the input voltage?
As stated previously, decreasing the input voltage will cause an increase in input current which leads to increased losses and heat, while reducing the operating temperature range and efficiency. To protect the power supply from catastrophic failure, the controllers often have protection built in to avoid certain conditions.
