APW7337

APW7337 3A 24V 340kHz synchronous Buck Converter Features General Description Wide Input Voltage from 4.5V to 24V APW7337 is a 3A synchronous buck converter with inte- 3A Continuous Output Current grated 85mΩ power MOSFETs. The APW7337 design Adjustable Output Voltage from 0.8V to 20V with a current-mode control scheme, can convert wide Intergrated High/Low Side MOSFET input voltage of 4.5V to 24V to the output voltage adjust- PFM/PWM mode Operation Fixed 340kHz Switching Frequency able from 0.8V to 20V to provide excellent output voltage regulation. The APW7337 is equipped with an automatic PFM/PWM Stable with Low ESR Ceramic Output Capacitors mode operation. At light load, the IC operates in the PFM Power-On-Reset Detection mode to reduce the switching losses. At heavy load, the Programmable Soft-Start IC works in PWM. Over-Temperature Protection The APW7337 is also equipped with Power-on-reset, soft- Current-Limit Pr...
