Overview
The LX7188 is 1.4MHz fixed frequency, currentmode,synchronous PWM buck (step-down) DC-DC converter, capable of driving a 1A load with high efficiency, excellent line and load regulation. The device integrates synchronous P-channel and N-channel power MOSFET switches with low on-resistance. They accept an input voltage range from 2.5V to 5.5V and will enter 100% duty cycle at dropout making them ideal for powering portable equipment that runs from a single Li-ion battery. A standard series of inductors are available from several different manufacturers optimized for use with the LX7188. This feature greatly simplifies the design of switch-mode power supplies. The converter includes standard safety features such as over-current, short-circuit and thermal shutdown protection. This device is available in a UDFN 2x2 6L package. Features: Input Supply Range: 2.5V to 5.5V Output Adjustable from 0.6V to VIN – 0.5V 100% Duty Cycle in Dropout Integrated NMOS & PMOS Switches Ourrent Mode Control 1A Maximum Output Current Fixed 1.4MHz Frequency High Efficiency: Up To 96% Built-in Soft-start Built-in OV, UV & OT Protection Built-in Short Circuit Protection RoHS Compliant & Halogen Free UDFN 2x2 6L Package Applications: IP Phones Wireless LAN Access Point Enterprise router Storage Magnetic Hard Disk Laptops |
