The devices work under the input voltage between 0.6V and 4.4V with a 1.5MHz fixed frequency switching. These features minimizes overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The kB3429 is capable of supplying an output voltage between 2.5V and 4.3V, the internal synchronous switch is desired to provide high efficiency without Schottky. The devices also featured providing up to 260mA from a single AA cell input or up to 600mA from a 2-cell AA with a 3V/3.3V output. The kB3429 regulators are available in the industry standard SOT-23-6 power packages (or upon request). kB3429 Kingbor Technology Co.,Ltd TEL:(86)0755-26508846 FAX:(86)0755-26509052 KB3429 Ver: 1.3 |
