ON Semiconductor's NCP1526 is a high efficiency synchronous DC-DC buck (step-down) converter that includes a low noise LDO. Offered in a unique 0,55 mm ultra-thin DFN package, the device is designed to power an application microprocessor in multimedia portable devices.
This NCP1526 buck converter accepts input voltages from 2,7 V to 5,2 V, and features a 3,0 MHz buck converter that supplies a fixed output voltage with current capability of 400 mA. It delivers fast transient response, making the converter ideal to power the digital core of a portable microprocessor. The device's integrated LDO provides a 150 mA current capability and its low noise characteristic enables it to power RF-sensitive analog circuitry. The NCP1526 offers a fixed output of 1,2 V from the converter and 2,8 V from the LDO.
The high frequency oscillator reduces the size of external components required. In fact, a very small surface mount inductor of value between 1 μH to 4,7 μH is recommended. These integrated regulators are packaged in a footprint of only 3 x 3 mm, saving 50% board space compared to a two-chip solution.
