MB39A108

FUJITSU has been putting a great deal of effort into the development of ICs for power managements in highperformance portable devices such as digital still cameras. for example MB39A108

Building on the technological foundation of eight predecessor series (MB3785A, MB3825A, MB3827, MB3881, MB3883, MB39A102, MB39A103, and MB39A110), the company has recently completed􀊠MB39A108􀊡, a 5-channel DC/DC converter IC with synchronous rectification. MB39A108 is optimal for multi power supply systems built-in highperformance portable devices.

With the ongoing advancement of high functionality in portable devices, the demand for the miniaturization of built-in power supplies will continue to grow. The MB39A108 is a 5- channel DC/DC converter IC with a synchronous rectification function based on the pulse width modulation type (PWM type). Up-conversion, down-conversion, and up/down conversion are all supported, and each of five channels built-in a TSSOP-38P package can be controlled and soft-started independently. A soft-start circuit and timer latch short-circuit detection circuit are also mounted to prevent inrush current at power start-up and overcurrent due to output short-circuits.

These features make MB39A108 optimal for power supplies in high-performance portable devices such as digital still cameras.
