Preliminary
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 soft start control and protection function,
such as Cycle-by-Cycle current limiting, Over Loading Protection,
Output Short-Circuit Protection, R_CS short Protection, OTP, V_DD
OVP, and UVLO.
 FEATURES
* Power on soft-start
* Load compensation
* Built-in error amplifier
* Oscillator of fixed frequency with frequency-reduction control
* Frequency shuffling for EMI improvement
* Built-in Leading Edge Blanking (LEB)
* Cycle-by-Cycle current limiting
* Over loading protection
* Output short-circuit protection
* V_DD Under Voltage Lockout with hysteresis (UVLO)
* V_DD OVP
