PD94649 IRU3039 SYNCHRONOUS PWM CONTROLLER WITH OVER CURRENT PROTECTION FEATURES Current Limit using Lower MOSFET Sensing Using the 6V internal regulator for charge pump circuit allows single supply operation up to 18V Programmable Switching Frequency up to 400KHz Soft-Start Function 0.
8V Precision Reference Voltage Available Uncommitted Error Amplifier Available for DDR Voltage Tracking Applications Stable with Ceramic Capacitor DESCRIPTION The IRU3039 controller IC is designed to provide a synchronous Buck regulator and is targeted for applications where the cost and size is critical.
The IRU3039 operates with a single input supply up to 18V.
The output voltage can be programmed as low as 0.
8V for low voltage applications.
Selectable current limit is provided to tailor to external MOSFET’s on-resistance for optimum cost and performance.
The IRU3039 features an uncommitted error amplifier for tracking output voltage and i...
