MPQ8616 High Efficiency, 6A/12A, 6V Synchronous Step-down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MPQ8616 is fully integrated high frequency 1.5V to 6V Wide Input Range synchronous rectified step-down switch mode 3 V to 6V VCC Operating Supply converter. It offers very compact solutions to 6A/12A Output Current achieve 6A/12A output current from a 3V to 6V Low R (ON) Internal Power MOSFETs DS input with excellent load and line regulation. Proprietary Switching Loss Reduction Technique Constant-On-Time (COT) control mode provides Adaptive COT for Ultrafast Transient fast transient response and eases loop Response stabilization. The MPQ8616 can operate with a 1% Reference Voltage Over -20 C to +85 C low-cost electrolytic capacitor and can support Junction Temperature Range ceramic output capacitor with external slope compensation. Programmable Soft Start Time Pre-Bias Start up Operating frequency is programmed by an Programmable Switching Frequency from external resistor and is compensated for 300kHz to 1MHz. variations in V . It is almost constant with all the IN Minimum On Time T =60ns ON MIN input voltage and output load conditions. Minimum Off Time T =100ns OFF MIN Under voltage lockout is internally set at 2.8 V, Non-latch OCP, non-latch OVP Protection but can be increased by programming the and Thermal Shutdown threshold with a resistor network on the enable Output Adjustable from 0.61V to 4.5V pin. The output voltage startup ramp is controlled by the soft start pin. A power good signal APPLICATIONS indicates the output is within its nominal voltage Telecom System Base Stations range. Networking Systems Full fault protection including OCP, SCP, OVP Server UVP and OTP is provided by internal Personal Video Recorders comparators. Flat Panel Television and Monitors Distributed Power Systems The MPQ8616 requires a minimum number of readily available standard external components and All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
