Embodiment Construction

[0030] The following is a further non-limiting detailed description of the technical solution of a programmable power conversion chip involved in the present invention in conjunction with preferred embodiments and accompanying drawings.

[0031] see figure 1 As shown, an embodiment of the present invention provides a programmable power conversion chip 1 , including a power conversion module 2 , a central control module 3 , an interface 4 and a memory 5 . The central control module 3 further includes a voltage value setting module 6 , a power on / off sequence control module 7 and a voltage range control module 8 .

[0032] Each of the power conversion modules 2 is the same component, so the same reference number 2 is used to refer to them. The figure is divided into various power conversion modules, just for clarity of description, and corresponding to the subsequent DC voltage outputs. Specifically, it can be AC-DC conversion or DC-DC conversion, and each power conversion modu...

Abstract

The invention discloses a programmable power conversion chip. The programmable power conversion chip comprises a central control module, a first power conversion module and a second power conversion module,wherein the first power conversion module and the second power conversion module are connected in parallel with the central control module for outputting a first direct current voltage and a second direct current voltage respectively. The central control module comprises an upper / lowerpower sequence control module, wherein the upper / lowerpower sequence control module is used for settingthe upper / lowerpower sequenceof the direct current output voltage of the first power conversion module and the second power conversion module. The programmable power conversion chip can carry out aprogrammable control on the upper / lowerpower sequence of multiple direct current output voltages. The programmable power conversion chip has the advantages of being high in safety, strong in controllability and simple in implementation.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a power conversion chip involved therein. Background technique [0002] With the rapid development of electronic technology, the application range of electronic systems is becoming wider and wider. The functional design inside the system is also becoming more and more complex, in order to achieve better use effect. [0003] Generally speaking, electronic systems generally adopt a DC power supply voltage, and with the enhancement of electronic system functions, more and more electronic systems need to adopt multiple DC power supply voltages. [0004] For electronic systems that require multiple DC power supply voltages, there are generally specific requirements for the power-on / off sequence and voltage range among multiple voltages. For example, the GaN power amplifier in the GaN power amplifier system has strict requirements on the power-on / off sequence and voltage range of t...
