产品概述 返回TOPUJq嘉泰姆
The CXLB7340 is a complete, cost effective, highly-efficient power management solution that is ideal for a wide range of portable UJq嘉泰姆
handheld equipment. This device integrates two PWM step-down DC/DC converters, four low-noise low-dropout linear regulators UJq嘉泰姆
(LDOs) and one battery charger in a single, thin, space-saving package. This device is ideal for a wide range of portable handheld UJq嘉泰姆
equipment that can benefit from the advantages of technology but does not require a high level of integration.UJq嘉泰姆
VBAT is a complete constant-current/constant voltage linear charger for one cell lithium-ion battery. The charge current of pre-charging UJq嘉泰姆
and constant–current charging is adjustable and it can be programmed to 700mA. An external resistor sets the charge current with UJq嘉泰姆
high accuracy.VOUT1 and VOUT6 is a fixed-frequency, current-mode PWM step-down DC/DC converters that are optimized for UJq嘉泰姆
high efficiency and is capable of supplying up to 500mA output current. VOUT2, VOUT3, VOUT4 and VOUT5 are low noise, highUJq嘉泰姆
