AOZ1282CI

AOZ1282CI EZBuck™ 1.2A Simple Buck Regulator General Description The AOZ1282CI is a high efficiency, simple to use, 1.2A buck regulator flexible enough to be optimized for a variety of applications. The AOZ1282CI works from a 4.5V to 36V input voltage range, and provides up to 1.2A of continuous output current. The output voltage is adjustable down to 0.8V. The fixed switching frequency of 450kHz PWM operation reduces inductor size. Features  4.5V to 36V operating input voltage range  420mΩ internal NMOS  Up to 95% efficiency  Internal compensation  1.2A continuous output current  Fixed 450kHz PWM operation  Internal soft start  Output voltage adjustable down to 0.8V  Cycle-by-cycle current limit  Short-circuit protection  Thermal shutdown  Small size SOT23-6L Applications  Telecom/Networking/Datacom equipment  Point of load DC/DC conversion  Set top boxes and cable modems  DVD drives and HDDs  LCD Monitors & TVs Typical Application VIN C1 EN C3 6 VIN BST 1 AOZ1282CI 4 EN LX 6 2 GND FB 3 L1 D1 R1 R2 Rev. 1.4 June 2022 Figure 1. 1.2A Buck Regulator www.aosmd.com VOUT C2 Page 1 of 13 AOZ1282CI Ordering Information Part Number AOZ1282CI Ambient Temperature Range -40 °C to +85 °C Package SOT23-6L Environmental Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
