Abstract

Provided is a multi-path separate DC stabilized voltage supply printed circuit board. In the prior art, DC power supply fluctuation is large and single. The multi-path separate DC stabilized voltage supply printed circuit board comprises: a single phase transformer (1), connected with a rectifier bridge (2), which is connected with a filter (3). The filter is connected with a three-end integratedvoltage stabilizer (4), connected with the filter. The filter is connected with a MAX1552 power chip (5) or connected with an indicating circuit (6). The MAX1552 power chip is connected with the indicating circuit. The product realizes output of the separate DC stabilized voltage supply.

Description

Technical field: [0001] The invention relates to a printed circuit board of a multi-channel detachable DC stabilized voltage power supply. Background technique: [0002] The function of the DC stabilized power supply is to convert the input AC power into a stable DC voltage output. Almost all electronic instruments and equipment require a stable DC voltage. Usually, the composition of a DC stabilized power supply includes: a power transformer, a rectifier, a filter, and a voltage stabilizer. The function of the transformer is to transform (usually step down) and isolate; the function of the rectifier circuit is to convert AC power into pulsating DC power; The function of the filter circuit is to filter out the AC components in the pulsating DC as much as possible to make the output voltage smooth; the function of the voltage regulator circuit is to stabilize the output voltage, that is, when the power supply voltage, load and ambient temperature change within a certain rang...

Usually, the composition of a DC stabilized power supply includes: a power transformer, a rectifier, a filter, and a voltage stabilizer. The function of the transformer is to transform (usually step down) and isolate; the function of the rectifier circuit is to convert AC power into pulsating DC power; The function of the filter circuit is to filter out the AC components in the pulsating DC as much as possible to make the output voltage smooth; the function of the voltage regulator circuit is to stabilize the output voltage, that is, when the power supply voltage, load and ambient temperature change within a certain range, The voltage stabilizing circuit can automatically adjust to keep the output DC voltage basically unchanged. In the traditional method, the output DC power fluctuates greatly and is relatively single.
