MP2153GTF-P Monolithic Power Systems

MP2153 5.5V, 3A, Sync Step-Down Converter with 25 A I and Output Discharge Q in Ultra-Small Package DESCRIPTION FEATURES The MP2153 is a monolithic, step-down, switch- Low I : 25A Q mode converter with built-in, internal power 1.1MHz Switching Frequency MOSFETs. The MP2153 achieves 3A of EN for Power Sequencing continuous output current from a 2.5V to 5.5V 1% FB Accuracy input voltage range with excellent load and line Wide 2.5V to 5.5V Operating Input Range regulation. The output voltage can be regulated Output Adjustable from 0.6V as low as 0.6V. Up to 3A Output Current The constant-on-time (COT) control scheme 65m and 35m Internal Power MOSFET provides fast transient response and eases loop Switches stabilization. Fault protections include cycle-by- 100% Duty On cycle current limiting and thermal shutdown. Output Discharge V Over-Voltage Protection (OVP) OUT The MP2153 is ideal for a wide range of Short-Circuit Protection (SCP) with Hiccup applications, including solid-state drives, Mode portable devices, and other low-power, low- Power Good (for Fixed Output Version voltage systems.
