MP3438 is a high-efficiency, fully integrated, synchronous boost converter. This highly integrated boost converter with a 1.2MHz fixed frequency and a wide input voltage (VIN) range. This starts up from a VIN as low as 2.7V, and can support up to a 2A switching current limit with integrated, low RDS(ON) power MOSFETs. It adopts constant-off-time (COT) control to provide fast transient response. The cycle-by-cycle current limit on the low-side MOSFET (LS-FET) prevents current runaway, and the high-side MOSFET (HS-FET) eliminates the need for an external Schottky diode. It supports an automatic pass-through function when VIN exceeds the set output voltage (VOUT-SET). This function supports high efficiency, even when the input exceeds the regulated output. Typical applications are LCD bias supplies, ADSLs/DSLs, electronic cigarettes, instrumentation equipment, portable applications.
