SC2953 is a monolithic synchronous buck regulator that integrates the on-resistance of 130 milliohms MOSFET, can be over a wide input voltage range (4.75V-23V) provides 3A of load capacity. Current mode control so that it has a good transient response and limiting functions within a single cycle. Adjustable soft-start time to avoid the opening moments of the impact of current in standby mode, the input current is less than 1uA. SC2953 package for SOP-8, while providing a compact system solution that can minimize external components. Main features: 1,3A output current 2, the input voltage range 3,4.75 to 18V 4, the output is adjustable from 0.923V to 15V 5, efficiency up to 93% 6, 7 adjustable soft-start time, the external use of low ESR ceramic chip capacitors ensure its stability 8, 450kHz fixed frequency, within each cycle current limiting function 9, 10 with undervoltage protection, thermal ability of the SOP-8 package Applications: 1, discrete power supply System 2, the network system 3, FPGA, DSP, ASIC power supply 4, 5 green electronic products, notebook computers Main Products: lithium rechargeable lithium battery management IC double single 8.4V rechargeable lithium-cadmium batteries tweezers mouse ultra-low power boost IC DC-DC regulator IC Car Charger Car Charger IC solutions Car LED lighting driver IC constant current output with a line of cars filling up car charger IC 60V high voltage regulator IC lithium battery charge management IC 3.7V 5V high current l l Pressure boost charger IC LED Driver IC IC IC urgent boost charge current regulator IC LED lights boost driver IC IC electric toys boost high efficiency DC-DC step-down IC Wide Input high current incandescent lamp driver IC LED flashlight l Pressure IC synchronous rectification IC synchronous buck IC DC / DC step-down IC solar lawn IC output adjustable low-voltage detector IC buck IC touch IC 8 key touch IC 6 key Touch Touch Touch IC IC IC key touch touch double bond 24-key touch-chip IC 36 key touch IC three-terminal regulator IC LDO LDO 22V power supply 40V buck buck LDO widely core source --- Luo Mobile: 13425146336 Tel: 0755-29469758 27668758 E-mail: mk003 @ zgsemi. com Website: http: //www.zgsemi.com
