UD05124 LINEAR INTEGRATED CIRCUIT
HIGH EFFICIENCY 1.5MHZ 1.2A SYNCHRONOUS STEP DOWN CONVERTER
DESCRIPTION
The UTC UD05124 is a high efficiency, high frequency synchronous DC-DC step-down converter. The 100% duty cycle feature provides low dropout operation, extending battery life in portable systems.
The internal synchronous switch increases efficiency and eliminates the need for external schottky diode. At shutdown mode, the input supply current is less than 1μA.
The UTC UD05124 fault protection includes over current protection, short circuit protection, UVLO and thermal shutdown. The Internal soft-start function prevents inrush current at turn-on.
FEATURES
UD05124 線性集成電路
高效 1.5MHZ 1.2A 同步降壓轉換器
描述
UTC UD05124 是一款高效率、高頻同步 DC-DC 降壓轉換器。 100% 佔空比功能提供低壓差操作,延長便攜式系統的電池壽命。
內部同步開關提高了效率並消除了對外部肖特基二極管的需求。在關斷模式下,輸入電源電流小於 1μA。
UTC UD05124 故障保護包括過流保護、短路保護、UVLO 和熱關斷。內部軟啟動功能可防止開啟時的浪湧電流。
