GENERAL DEscriptION
The SGM6010 is a synchronous, buck DC/DC converter with a range of 3V to 5.5V input voltage. This device is capable to provide a 3A continuous output current. It operates with a programmable frequency range of 300kHz to 2MHz. The SGM6010 is highly efficient with peak efficiency at 95% when in operation. The duty cycle could make the lowest dropout.
The forced continuous pulse width modulation (PWM) mode operation could decrease the ripple voltage to the lowest level and reduce noise and RF interference as well. No external power MOSFETs and Schottky diode are required because of the internal synchronous low on-resistance power switches. The external compensation can improve the transient response across the loads and output capacitors.
The SGM6010 is available in a Green TDFN-3×3-10L package. It is rated over the -40℃ to +85℃ temperature range.
