FemtoBuck® DC-DC Regulators and Controllers
Compact in size, the efficient FemtoBuck platform is ideal for small form factor portable applications where long battery life is essential. These buck regulators are adaptive on-time 4MHz switching regulators at full load conditions. Under light load conditions, the regulators seamlessly transition into power save mode which reduces switching frequency and saves energy. High switching frequency operation allows the use of a very small 0.47μH indicator along with small input and output capacitors to minimize overall circuit size. Key features include adjustable output voltage, pre-bias startup protection, internal soft start, and a power good indicator.
