NX4110CZ1TR (#322500) |
|
Overview
The NX4110 is a current mode PWM buck switcher with internal compensation that can provide up to 1A output current with the FET on board. It operates from 2.8V to 5.5V Vin with an output voltage as low as 0.6V making it ideal for applications using single cell Li-Ion batteries as well as other 3.3V input bus supply applications. Switching frequency is fixed at 1MHz. Small surface mount inductors and capacitors can be used with the NX4110, making it ideal for portable applications. The NX4110 is available in 5-pin SOT23 package. FEATURES: o SOT23-5L package o Internal Digital Soft Start o Internally-compensated Current Mode Controller o Peak Current Limit with HICCUP Feature and Over Temperature Protection o Prebias Start-up Operation o Pgood Available APPLICATIONS: o Li-Ion battery operated portable system o Cellular Phones o Portable applications o USB Devices |
