It is designed to meet the needs of power-saving applications such as embedded systems, DVRs, and audio/video systems. It also provides superior performance for low-to-medium current applications such as portable power systems.

The main application field of the ISL9113EI9Z-T is in devices requiring a power supply with high-performance and low EMI. Typical application of this IC includes embedded devices such as tablet PCs, digital cameras and PDA. It also provides superior performance for portable power applications like laptop PCs, GPS systems and cellular phones.

The ISL9113EI9Z-T is a DC-DC switching regulator that can be used to create the required output voltage and current. It consists of an internal P-channel FET and N-channel FET, which acts as the switch in the converter. It can operate in two modes: continuous conduction mode (CCM) or discrete frequency mode (DFM). In CCM, the converter is in a constant operating condition, which is suitable for supplying high current loads. In DFM, the FETs are used in a pulse width modulation mode to create the required output voltage and current. The output voltage is set via a voltage divider connected to the external sense input pins. The device can also incorporate system-level power saving features, such as pulse-width modulation (PWM) dimming.

The ISL9113EI9Z-T is capable of operating at a switching frequency up to 1.2MHz. This enables the device to provide very high level of efficiency and low output ripple. It also features an adjustable switching frequency, integrated soft start, power good output and under-voltage lockout.

In summary, the ISL9113EI9Z-T is a low-cost and high-performance DC-DC switching regulator. Its main application is in applications requiring high-performance and low EMI, such as embedded systems, tablet PCs, digital cameras and PDA. Its PWM dimming feature and adjustable switching frequency make it an ideal choice for power-saving applications like portable power systems. As such, it is an excellent choice for system power supply solutions.
