UD05104
DESCRIPTION
The UTC UD05104 is a 1A high frequency synchronous Step Down DC/DC converter using constant frequency, current mode architecture. The device integrates main switch and synchronous rectifier switch for high efficiency without an external schottky diode. To maximize light load efficiency, The UTC UD05104 draws only 30μA quiescent current to improve light load efficiency. In shutdown, The UTC UD05104 reduces supply current less than 1μA. The UTC UD05104 can supply 1A of load current from 2.5V to 6.0V input voltage. The output voltage can be regulated as low as 0.6V. The switching frequency is internally set at 2.25MHz, as for operation mode: UTC UD05104 is automatic PSM/PWM mode.
The UTC UD05104 has built-in internal Soft Start, Short Circuit Protection and OTP functions, allowing the use of small surface mount inductors and capacitor.
