5 Description (continued)

The devices operate in the newly developed LinSkip mode. In this operating mode, the device switches seamlessly from the power saving pulse-skip mode at light loads to the low-noise constant-frequency, linear-regulation mode once the output current exceeds the LinSkip threshold of about 7 mA. Even in pulse-skip mode, the output ripple is maintained at a very low level because the output resistance of the charge pump is still regulated.

Three operating modes can be programmed using the EN pin. EN = low disables the device, shuts down all internal circuits, and disconnects the output from the input. EN = high enables the device and programs it to run from the internal oscillator. The devices operate synchronized to an external clock signal if EN is clocked; thus, switching harmonics can be controlled and minimized. The devices include a low-battery detector that issues a warning if the battery voltage drops below a user-defined threshold voltage, or a power-good detector that goes active when the output voltage reaches about 90% of its nominal value.

Device options with either a low-battery or power good detector are available. This dc/dc converter requires no inductors, therefore, EMI of the system is reduced to a minimum. It is available in the small 10-pin MSOP package (DGS).
