Power Electronics / Power Management
A new high efficiency synchronous DC-DC buck (step-down) converter in a unique 0,55 mm ultra-thin DFN package, which features an integrated low noise LDO, is being offered by On Semiconductor. Ideal for portable applications, the device is designed to power an application microprocessor in multimedia portable devices.
This new NCP1526 integrated buck converter accepts input voltage 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 it suitable for powering 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.
To ensure optimal component size and safe operation, value added features like soft-start, cycle-by-cycle current limiting, and thermal shutdown protection have also been integrated.
