GENERAL DEscriptION

The SGM6607A is a high voltage switching regulator. It integrates a 40V low-side MOSFET to offer an output voltage up to 38V. It also accepts a wide input voltage range of 3V to 20V from multi-cell batteries or regulated 5V/12V power rails. A 1.1MHz switching frequency makes the use of low-profile inductors and low-value ceramic input and output capacitors available.

The device supports Boost, SEPIC and some other standard switching-regulator topologies. The device regulates the output with PWM (pulse width modulation) control. This device also includes the built-in functions of over-current limit, soft-start and thermal shutdown.

The SGM6607A is available in Green TDFN-2×2-6AL and TSOT-23-6 packages and is rated over the -40℃ to +85℃ temperature range.
