Description
The buck-boost operation achieved by this combination of LDO and boost preregulator offers the advantage of using a single off-the-shelf inductor in place of the multiple- winding custom magnetics needed in typical single- ended primary inductor converter (SEPIC) and transformer-based flyback topologies. The high operating frequency of the boost regulator significantly reduces component size. The MAX5092_ integrates a blocking diode to further reduce the external component count. The boost preregulator output voltage is preset to 7V. Both LDO and boost output voltages are programmable using external resistors. The boost preregulator output voltage is adjustable up to 11V (MAX5092_), or up to 12V (MAX5093_). The LDO output voltage is adjustable from 1.5V to 9V (MAX5092_) or from 1.5V to 10V (MAX5093_).
The devices feature a shutdown mode with 5µA (typ) shutdown current, a active-low HOLD input to implement a self-holding circuit, and a power-on-reset output (active-low RESET) with an externally programmable timeout period. Additional features include output overload, short-circuit, and thermal protection.
The MAX5092_/MAX5093_ are available in a thermally enhanced, 16-pin 5mm x 5mm thin QFN package and can dissipate up to 2.7W at +70°C on a multilayer PC board.
