Car Charger DC-DC step-down IC CX8507 5V 4.2A Car Charger IC

CX8507 5V 4.2A Car Charger IC Overview CX8507 is a PWM synchronous rectification controller that drives N-channel MOSFET. CX8507 is a DC-DC step-down chip, used in notebook computer chips or RAM. CX8507 provides good transient response and accurate DC voltage output in PFM or PWM mode. Have provided the pulse frequency mode (PFM) at light to heavy loads, load switching frequency modulation efficiency is very high. Converter operates in almost constant frequency PWM mode and low noise characteristics require an adjustable output voltage range: + 0.7V to + 5.5V reference voltage temperature accuracy of ± 1% 0.7V battery input voltage range of + 1.8V to + 32V work Power-on reset monitor VCC pin good line and load transient response PFM mode to improve light load efficiency PWM mode selectable Integrated MOSFET Drivers TDFN-10 3x3 package Notebook Tablet PC handheld portable one computer LCD monitor / TV Battery Charger ADSL modem Telecom / Network Equipment Contact: 15989861461 QQ: 283860588 Gong Pingping
