1 / 6 page UNISONIC TECHNOLOGIES CO., LTD US2651 Preliminary CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2014 Unisonic Technologies Co., Ltd QW-R502-B23.b HIGH PRECISION LOW COST MCM POWER SWITCH 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, 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 DIP-8 SOP-8 ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free US2651L-D08-T US2651G-D08-T DIP-8 Tube - US2651G-S08-R SOP-8 Tape Reel US2651L-D08-T (1)Packing Type (2)Package Type (1) T: Tube, R: Tape Reel (2) D08: DIP-8, S08: SOP-8 (3) L: Lead Free, G: Halogen Free and Lead Free (3)Green Package |
