SLM6240AB-13GTR

The SLM6240 devices are high-performance, fixed frequency, current-mode PWM step-up DC/DC converters that incorporate internal power MOSFETs. The SLM6240 includes an integrated 80 mΩ power switch that supports peak currents of up to 4A. The device is capable of providing an output voltage up to 24 V. The SLM6240 uses peak current control topology to regulate the output voltage. In moderate to heavy load condition, the SLM6240 works in the pulse width modulation (PWM) mode. In light load condition, the device works in the pulse frequency modulation (PFM) mode to improve the efficiency. The SLM6240 utilizes simple external loop compensation allowing optimization between component size, cost and AC performance across a wide range of applications. Additional functions include an externally programmable soft-start function for easy inrush current control, internal overvoltage protection (OVP), cycle-by-cycle current limit protection, under voltage lock-out and thermal shutdown. The SLM6240 is available in the small SOIC8-EP package.
