DC-DC converter family with negative outputs
The XC9307 / XC9308 series are negative voltage output DC-DC converter modules measuring only 1.8×2.0x0.4mm.
The mounting area is reduced by approximately 70 percent (65.25mm2 to 19.11mm2) compared to general negative voltage output DC-DC converter, which can contribute to downsizing and thinning of electronic devices.
Compared to a charge pump type solution, the switching method of the XC9307/XC9308 maintains a stable output voltage even when the input voltage fluctuates. In addition, the DC-DC converter design supports a maximum output current of 300mA (when VIN = 3.3V, VOUT = -3.0V).
The output voltage can be adjusted within the range of -1.2V to -6.0V using externally mounted resistors. The PWM controlled XC9307 series can be selected for applications where low noise is important, and the PWM/PFM automatic switching controlled XCL304 XC9308 series can be selected for applications where high efficiency at light load current and low noise at high load current is important.
