The SGM6612A is a 20V high-efficient synchronous Boost converter integrated with two 15mΩ power switches. This device offers small size power solution for portable equipment. The device has high switching frequency up to 2.2MHz with resistor programmable.
The SGM6612A has two operation modes, the pulse width modulation (PWM) mode and pulse frequency modulation (PFM). The PWM mode is applied at moderate to heavy load. The PFM mode is applied at light load to improve the efficiency.
The SGM6612A features a built-in gate driver for external MOSFET, which can isolate the output from the input when the device shuts down or in output short condition. When the output is shorted and the short protection is triggered, the device goes to the hiccup mode for safety. In addition, the device also provides output over-voltage protection, inductor current limit protection and thermal shutdown.
The SGM6612A is available in a Green TQFN-3×3.5-13L package.
