The SGM6630 is a wide VIN, high-performance, non-synchronous Boost controller. The device is capable to support Boost, SEPIC and Flyback topologies with a low-side FET as the main switch. The device has a high adjustable and synchronizable clock frequency range from 100kHz and 1MHz to reduce the overall solution size. In addition to the cycle-by-cycle current limit, the current mode operation also provides superior bandwidth and transient response. The current limit threshold can be programmed by a single external resistor. The integrated current slope compensation makes the design process simplified.
The SGM6630 equips the built-in protection features such as thermal shutdown, internal soft-start, over-voltage protection and short-circuit protection. It consumes 3μA current in shutdown mode. The internal soft-start function can limit the inrush current when the device is turned on.
The SGM6630 is available in a Green MSOP-10 package.
