Keywords:micro one? dc/dc converter? dc converter? me301?

The ME301 step-up dc/dc converter IC enables the construction of a low-ripple, high-efficiency step-up dc/dc converter module with only three external components. It incorporates an oscillator, a VFM control circuit, a Lx switch driver transistor and protection circuit, a reference voltage unit, an error amplifier, and resistors for voltage detection.

Operating on ultra-low supply current, the device is suitable for battery-powered instruments requiring low noise and ultra-low supply current. Applications include cameras, camcorders, VCRs, PDAs and handheld communication devices and power sources for appliances.

No-load input current is rated at only 65A (typ.). The chip exhibits a high output voltage accuracy of 2.5 percent. Typical efficiency is specified at 80 percent.

The ME301 is housed in an SOT-89.
