SGM3209 High Voltage, Charge Pump DC/DC Converter GENERAL DESCRIPTION FEATURES The SGM3209 is a charge pump voltage converter ● Input Voltage Range: 3V to 18V which is used to generate a negative supply from a ● Output Current: 100mA positive input. The 3V to 18V input voltage can be ● Pull-Low Resistor on EN Pin: 600kΩ converted into a corresponding -3V to -18V output ● Programmable Oscillator Frequency: 120kHz to 1.25MHz supply. The SGM3209 is also capable of delivering up to 100mA of output current. The switching frequency is ● No External Diodes Required resistor programmable from 120kHz to 1.25MHz. The ● Low Output Impedance: 15Ω (TYP) at IOUT = 20mA device also has the advantage of using a combination ● CMOS Construction of few external components to eliminate the inductors ● -40℃ to +85℃ Operating Temperature Range and their associated cost, size and EMI. ● Available in Green TDFN-2×2-8L and SOIC-8 Packages The SGM3209 enters into shutdown status by external enable control signal to reduce system power dissipation. The device is used for design requirements with higher output current and/or lower input/output APPLICATIONS Laptop Computers voltage drop. The SGM3209 is available in Green TDFN-2×2-8L and SOIC-8 packages. It operates over an ambient Disk Drives Process Instrumentation temperature range of -40℃ to +85℃.
