DESCRIPTION
The UTC To maximize light load efficiency, The UTC UD05104A draws only 30μA quiescent current to improve light load efficiency. In shutdown, The UTC UD05104A reduces supply current less than 1μA. The output voltage can be regulated as low as 0.6V. The switching frequency is internally set at 1MHz, as for operation mode: UTC UD05104A is automatic PSM/PWM mode. The UTC UD05104A has built-in internal Soft Start, Short Circuit Protection and OTP functions, allowing the use of small surface mount inductors and capacitor.●
