SGM660 Buck-Boost Converter for Negative Output Voltage
●The SGM660 is an inverting buck-boost converter with adjustable negative output voltage in a tiny 6-ball thin WLCSP package. Its unique control method is designed to provide fast transient response, low output noise and high efficiency. The SGM660 has built-in soft-start, peak current limit, and under-voltage lockout functions with no external compensation required. For ease of use, the digital interface control (SWIRE) pin allows programming of the negative output voltage in digital steps.
■FEATURES:
●2.8V to 5.5V Input Voltage Range
●Adjustable Output Voltage: -0.8V to -5.2V, 0.1V/Step
●Programmable Switching Current Limit: 810mA (Default)/620mA/435mA
●Programmable Switching Frequency: 1.8MHz/1.6MHz (Default)/1.4MHz
●No External Compensation
●Internal Soft-Start Function
●Shutdown Current: 1μA (MAX)
●Available in a Green WLCSP-0.9×1.3-6B Package
