SGM66075A
Low-IQ, High Efficiency 9A Valley Current Synchronous Boost Converter with Bypass Switch
The SGM66075A is a high power density synchronous Boost converter with integrated low RDSON bypass switch from the input to output. The device operates with 2MHz (TYP) switching frequency in Boost mode. At light load, the device operates in I2C programmable PFM mode to maximize efficiency.
The SGM66075A has a wide input range from 2.3V to 5.5V. After startup, the device is capable to operate down to 2.1V input before shutdown. Boost output voltage is programmable from 2.85V to 5.0V via I2C interface with 50mV step.
During operation, when the input voltage is higher than the programmed output voltage, the SGM66075A operates in bypass mode via the integrated low RDSON bypass switch to maximize the system efficiency. The current limit of bypass switch can be programmed to 11.2A (TYP) with 1µs (TYP) deglitch or 7.7A (TYP) with 1ms (TYP) deglitch.
When EN pin is pulled to logic high, the SGM66075A can be programmed in auto bypass mode, forced bypass mode or low power bypass mode. In auto bypass mode, when the input voltage falls below or rises above the programmed output voltage, the device automatically switches to either Boost or bypass mode to maintain the output voltage regulation. In low power bypass mode, the device will turn off more circuits to achieve lower quiescent current than forced bypass mode.
The maximum I2C programmable Boost valley current limit of SGM66075A is 9A (TYP). For high pulsating load applications, the device is capable to support 5A peak current at 3.4V output when the input source voltage drops to 2.7V.
The SGM66075A is available in a Green WLCSP- 1.73×1.73-16B package.
