P1484A LINEAR INTEGRATED CIRCUIT
3A, 23V, 340KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER
DESCRIPTION
FEATURES
P1484A 線性集成電路
3A, 23V, 340KHZ 同步整流降壓轉換器
描述
UTC P1484A 是一款同步降壓穩壓器。該器件在 5V~23V 的寬輸入電壓範圍內提供 3A 的連續負載電流。電流模式控制提供快速瞬態響應和逐週期電流限制。可調軟啟動可防止開啟時的浪湧電流
UTC P1484A 可提供低紋波功率、高效率和完美的瞬態特性。在 PWM 控制中，佔空比從 0% 到 92% 線性變化。該器件中包含的誤差放大電路和軟啟動電路可以防止啟動時的過衝。內部還內置了使能功能、過流保護（OCP）功能和短路保護（SCP）功能，當發生OCP時，操作頻率會降低。
特徵
3A, 23V, 340KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER
DESCRIPTION
The UTC P1484A is a synchronous buck regulator. Thedevice provides3A of continuous load current over a wide input voltage of 5V~23V. Current mode control provides fast transient response and cycle-bycycle current limit. An adjustable soft-start prevents inrush current at turn-on
The UTC P1484A can provide low-ripple power, high efficiency, and perfect transient characteristics. The duty ratio varies linearly from 0% to 92% in the PWM control. The error amplifier circuit and soft-start circuit included in this device can prevent overshoot at startup. An enable function, an over current protect (OCP) function and short circuit protect (SCP) are also build inside, and when OCP happens, the operation frequency will be reduced.
