Preliminary

CMOS IC

HIGH PRECISION LOW COST

MCM POWER SWITCH



DESCRIPTION

The UTC US2351 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 US2351 use UTC

proprietary frequency shuffling technique for EMI performance. And

oscillator with frequency-reduction control is implemented.

The UTC US2351 has soft start control and protection function,

such as Cycle-by-Cycle current limiting, Over Loading Protection,

Output Short-Circuit Protection, R_CSshort Protection, OTP, V_DD

OVP, and UVLO.

SOP-8


