XCL301

XCL301Series ETR28015-003 Inductor Built-in Inverting “micro DC/DC” Converters ☆Green Operation Compatible ■GENERAL DESCRIPTION The XCL301 series is a inverting micro DC/DC converter which integrates a P-channel FET, an inductor and a control IC in one tiny package (2.5mm×2.0mm, h=1.00mm max). A wide operating voltage range of 2.7V to 5.5V enables support for applications that require an internally -3.3V fixed output voltage. The XCL301 series uses automatic PFM/fixed off time PWM. In automatic PFM/fixed off time PWM control, the IC operates by PFM control when the load is light to achieve high efficiency over the full load range from light to heavy. The device provides a stable inverting power supply to be configured using only a SBD and two capacitors connected externally. During stand-by, all circuits are shutdown to reduce current consumption to as low as 0.1μA or less. With the built-in UVLO function, the internal P-channel MOS driver transistor is forced OFF when input voltage becomes 2.2V or lower. The XCL301 integrate CL High Speed discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge. ■APPLICATIONS ● Negative power supply for AMP ● Negative power supply for LCD ● Negative power supply for CCD ● General purpose Negative power supply ■FEATURES Input Voltage Range : 2.7V ~ 5.5V Output Voltage : -3.3V Output Voltage accuracy ±2.0% Output Current : -50mA@VOUT=-3.3V, VIN=3.3V (TYP) Internal...
