The SGM61223 is an adaptive constant on-time control (ACOT) synchronous Buck converter with a wide input voltage range of 4.5V to 28V. This device has 2A output current capability and operates at pseudo-fixed frequency. It is an easy-to-use device with power switches and internal compensation circuit, which are all integrated in a small 6-pin package, and supports low-equivalent series resistance (ESR) output capacitors. A typical 3ms soft-start ramp is also included to minimize the inrush current.
Protection features include cycle-by-cycle current limit, hiccup current-protection mode, output over-voltage protection and thermal shutdown in case of excessive power dissipation.
The SGM61223A-ADJ enters in pulse-skip mode (PSM) to improve efficiency during light load operation.
The SGM61223 is available in a Green TSOT-23-6 package.
