nchronous, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to provide a 2A continuous current over a wide input supply range, with excellent load and line regulation. H9118 achieves low EMI signature with well controlled switching edges. Fault condition protection includes programmable-output over-voltage protection, Constant on time Mode, and thermal shutdown. H9118 requires a minimal number of readily available standard external components. It is available in TSOT23-6 package. Features ● Wide 4.0V to 18V Operating Input Range ● 2.
