MPQ8632 High Efficiency 18V Synchronous Step-down Converter Family for 4A to 20A The Future of Analog IC Technology Current FEATURES Part Number Input Voltage OVP Mode Rating (A) Low Input Voltage Range from 2.5V: MPQ8632GLE-4 4 2.5V to 18V Non-Latch -- 2.5V to 18V with External 5V Bias MPQ8632GLE-6 6 2.5V to 18V Non-Latch -- 4.5V to 18V with Internal Bias MPQ8632GLE-8 8 2.5V to 18V Non-Latch Scalable Family of Products for 4A to 20A MPQ8632HGLE-10 10 2.5V to 18V Non-Latch Output Current Applications MPQ8632GLE-10 10 2.5V to 18V Latch-Off -- 4A/6A/8A/10A/12A Share the Same 12 2.5V to 18V Non-Latch MPQ8632GLE-12 Footprint 15 2.5V to 18V Non-Latch --15A/20A Share the Same Footprint, with MPQ8632GVE-15 20 2.5V to 18V Non-Latch Slight Change on Power Stage Section MPQ8632GVE-20 from 4A/6A/8A/10A/12A Optimal Low R (ON) Internal Power DS DESCRIPTION MOSFETs Per Device The MPQ8632 is a fully integrated high Proprietary Switching Loss Reduction frequency synchronous rectified step-down Technique switch mode converter. It offers a very compact Adaptive COT for Ultrafast Transient solution to achieve 4A/6A/8A/10A/12A/15A/20A output current over a wide input supply range Response with excellent load and line regulation. 0.5% Reference Voltage Over 0 C to The MPQ8632 uses Constant-On-Time (COT) 70 C Junction Temperature Range control mode to provide fast transient response Programmable Soft Start Time and ease loop stabilization. Pre-Bias Start up An external resistor programs the operating Programmable Switching Frequency from frequency from 200kHz to 1MHz and the 200kHz to 1MHz frequency keeps nearly constant as input Non-latch OCP, OVP and Thermal supply varies with the feedforward Shutdown Protection compensation. Output Adjustable from 0.611V to 13V The default under voltage lockout threshold is internally set at 4.1V, but a resistor network on the enable pin can increase this threshold. The APPLICATIONS soft start pin controls the output voltage startup Telecom and Networking Systems ramp. An open drain power good signal Base Stations indicates that the output is within nominal Servers voltage range. Personal Video Recorders It has fully integrated protection features that Flat Panel Television and Monitors include over-current protection, over-voltage Distributed Power Systems protection and thermal shutdown. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green status, please visit MPS website under Products, Quality Assurance page.
