UD05158中文资料1.5A, LOW NIOSE 1.5MHZ SYNCHRONOUS STEP-DOWN CONVERTER数据手册UTC规格书

描述 Description

The UTC UD05158 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 1.5A continuousoutput current over from 2.7V to 5.5V input supply range, with excellent load and line regulation. The output voltage is adjustable from 0.6V to the input voltage. During shutdown, the input is disconnected from the output and the shutdown current is less than 1uA. Other key

特性 Features

include over-temperature and short circuit protection, and under-voltage lockout to prevent deep battery discharge. The UTC  UD05158 at 1.5A maximum output current while consuming only 200μA of no-load quiescent current. Ultra-lowRDS(ON) integrated MOSFETs   and 100% duty cycle operation make the UTC  UD05158  an ideal choice for high-output voltage, high-current applications which require a low dropout threshold.   FEATURES   Output Current : Up to 1.5A Output Voltage : 0.6V to VIN Input Voltage : 2.7V to 5.5V Low-RDS(ON) Internal Power MOSFETs. High-Efficiency Synchronous-Mode Operation, up to 95% 200uA (typ.) No Load Quiescent Current Shutdown Current < 1µA 100% Duty Cycle Operation Fixed 1.5MHz Switching Frequency. Current Mode Operation Internal Soft-Start. Current Limit Protection   Over-temperature Protection. Input Under Voltage Lockout (UVLO)
