摘要： A DC/DC converter and a series regulator are connected in parallel between an input terminal and an output terminal. At the time of a heavy load, the DC/DC converter is operated. Although the DC/DC converter has a large current consumption of its own, it has a high power conversion efficiency. Accordingly, since a load current increases at the time of a heavy load, it is effective to use the DC/DC converter whose power conversion efficiency is high, and its current consumption can be neglected since the load current is large. On the other hand, at the time of a light load, the series regulator is operated. Although the series regulator has a small current consumption of its own, it has a low power conversion efficiency. Accordingly, at the time of a light load, even when the series regulator is used, its low power conversion efficiency can be neglected because its current consumption is small. Accordingly, the current consumption of its own can be lowered at the time of a light load, and the power conversion efficiency as a whole can be improved when it is used both at a heavy load and a light load.
摘要翻译： DC / DC转换器和串联调节器并联连接在输入端子和输出端子之间。在重负载时，DC / DC转换器工作。虽然DC / DC转换器本身具有大的电流消耗，但是它具有很高的功率转换效率。因此，由于负载电流在重负载时增加，所以使用功率转换效率高的DC / DC转换器是有效的，并且由于负载电流大，所以能够忽略电流消耗。另一方面，在轻负载时，串联调节器被操作。虽然串联稳压器本身具有较小的电流消耗，但它具有低功率转换效率。因此，在轻负载时，即使使用串联调节器，由于其电流消耗小，所以其低功率转换效率可以忽略。因此，在轻负载时可以降低其自身的电流消耗，并且当在重负载和轻负载下使用时，可以提高整体的电力转换效率。

摘要： A programmable nonvolatile memory apparatus having a simplified circuit structure that eliminates a built-in sequencer circuit using a register (102) as a source of generating control signals required for writing data in and erasing data from an EEPROM (101). The register (102) is provided from outside a microcomputer (10) with a register address value inputted through an address bus (103), and a data value inputted through a register bus (104), and also register control signals, such as, a register write signal (105), a register read signal (106) and a register reset signal (107). The register (102) includes flip-flops. From the flip-flops, address data and rewriting data are outputted through buses (115, 116), and in addition, PRPM control signals (108 to 111, 117 and 118) are also outputted. The address space of the register (102) and the address space of the EEPROM (101) are separated from each other.
