Overview
UNISONIC TECHNOLOGIES CO.
, LTD UC2000D Preliminary HIGH PRECISION LOW COST MCM POWER SWITCH CMOS IC  DESCRIPTION The UTC UC2000D 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 UC2000D use UTC proprietary frequency shuffling technique for EMI performance.
And oscillator with frequency-reduction control is implemented.
The UTC UC2000D has soft start control and protection function, such as Cycle-by-Cycle current limiting, Over Loading Protection, Output Short-Circuit Protection, RCS short Protection, OTP, VDD 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 * VDD Under Voltage Lockout with hysteresis (UVLO) * VDD OVP  ORDERING INFORMATION Ordering Number UC2000DG-AG6-R Package SOT-26 54 6 1 23 SOT-26 Packing Tape Reel UC2000DG-AG6-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) AG6: SOT-26 (3) G: Halogen Free and Lead Freee  MARKING www.
