The independent enable pin for each output allows for simple and effective power sequencing. LM3370 is available in a 4mm by 5mm 16-lead non-pullback WSON and a 20-bump DSBGA, 3.0mm x 2.0mm x 0.6mm, package. A high switching frequency—2 MHz (typ)—allows use of tiny surface-mount components including a 2.2µH inductor. Default fixed voltages for the 2 output voltages combination can be customized to fit system requirements by contacting Texas Instruments.
