HIGH PRECISION LOW COST MCM POWER SWITCH
CMOS IC
DESCRIPTION
The UTC US2651 is a high performance, high precision and low cost PWM Power switch for non-isolated buck application. It combines a dedicated current mode PWM controller and error amplifier for low component count. UTC US2651 use UTC proprietary frequency shuffling technique for EMI performance. And oscillator with frequency-reduction control is implemented.
The UTC US2651 has sof
