Additional Infomation About Product

MP21148 1A, Synchronous, Step-Down Converter with CCM DESCRIPTION FEATURES The MP21148 is a monolithic, step-down, 2.4MHz Switching Frequency switch-mode converter with built-in, internal EN for Power Sequencing power MOSFETs. It can achieve 1A of Wide 2.3V-to-5.5V Operating Input Range continuous output current from a 2.3V-to-5.5V Output Adjustable from 0.6V input voltage with excellent load and line Up to 1A of Output Current regulation. The output voltage can be regulated 120m and 80m Internal Power MOSFET as low as 0.6V. Switches Output Discharging The constant-on-time control scheme in forced CCM provides a fast transient response, low 100% Duty Cycle output voltage ripple, and eases loop Short-Circuit Protection (SCP) with Hiccup stabilization. Fault protections include cycle-by- Mode cycle current limiting and thermal shutdown. Stable with Low ESR Output Ceramic Capacitors The MP21148 is available in an ultra-small Available in a QFN-6 (1.0mmx1.5mm) QFN-6 (1.0mmx1.5mm) package and requires Package a minimal number of readily available, standard, Continuous Conduction Mode (CCM) external components. APPLICATIONS The MP21148 is ideal for a wide range of applications including high-performance DSPs, Wireless/Networking Cards wireless power, portable and mobile devices, Portable and Mobile Devices and other low-power systems. Battery-Powered /Wearable Devices Low-Voltage I/O System Power All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
