Cxsu63130 series DC / DC chips are low static current PFM switching DC / DC boost converters manufactured by CMOS technology. This series of chips adopt advanced circuit design and manufacturing technology, which greatly improves the inherent noise problem of the switch circuit and reduces the interference to the surrounding circuit. The output voltage is 2.0V ~ 7.0v (according to the level difference of 0.1V), and the oscillation frequency is 100kHz (typical value). For the cxsu63130xx with built-in switch transistor, only three peripheral components, one Schottky diode, one inductor and one capacitor, are needed to form the DC / DC boost circuit. Cxsu63130cxx with CE terminal has the function of turning off, which can minimize the power consumption of the chip. This series of chips are suitable for low noise and high power
Streaming battery powered devices.
