MP2153GTF-P

MP2153 5.5V, 3A, Sync Step-Down Converter with 25μA IQ and Output Discharge in Ultra-Small Package DESCRIPTION FEATURES The MP2153 is a monolithic, step-down, switchmode converter with built-in, internal power MOSFETs. The MP2153 achieves 3A of continuous output current from a 2.5V to 5.5V input voltage range with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.         The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-bycycle current limiting and thermal shutdown. The MP2153 is ideal for a wide range of applications, including solid-state drives, portable devices, and other low-power, lowvoltage systems. The MP2153 requires a minimal number of readily available, standard, external components and is available in ultra-small SOT563 (1.6mmx1.6mm) or UTQFN-6 (1.2mmx1.6mm) packages.       Low IQ: 25μA 1.1MHz Switching Frequency EN for Power Sequencing 1% FB Accuracy Wide 2.5V to 5.5V Operating Input Range Output Adjustable from 0.6V Up to 3A Output Current 65mΩ and 35mΩ Internal Power MOSFET Switches 100% Duty On Output Discharge VOUT Over-Voltage Protection (OVP) Short-Circuit Protection (SCP) with Hiccup Mode Power Good (for Fixed Output Version Only) Available in SOT563 (1.6mmx1.6mm) or UTQFN-6 (1.2mmx1.6mm) Packages APPLICATIONS     Solid-State Drives (SSD) Portable Instruments Battery-Powered Devices Multi-Function Printers All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.

Output switching node. SW is the drain of the internal, high-side, P-channel MOSFET. Connect the inductor to SW to complete the converter. Supply voltage. The MP2153 operates from a +2.5V to +5.5V unregulated input. Use a decoupling capacitor to prevent large voltage spikes from appearing at the input. On/off control. Feedback. An external resistor divider from the output to GND tapped to FB sets the output voltage. Power good indicator. The output of PG is an open drain with an external pull-up resistor to VIN. Output sense. OUT is the voltage power rail and input sense pin for the output voltage. An output capacitor is needed to decrease the output voltage ripple. θJA θJC ABSOLUTE MAXIMUM RATINGS (1) Thermal Resistance Supply voltage (VIN) .................................... 6.5V VSW ................................ -0.3V (-5V for
