The CXLB7340 is a complete, cost effective, highly-efficient power management solution that is ideal for a wide range of portable 

handheld equipment. This device integrates two PWM step-down DC/DC converters, four low-noise low-dropout linear regulators 

(LDOs) and one battery charger in a single, thin, space-saving package. This device is ideal for a wide range of portable handheld 

equipment that can benefit from the advantages of technology but does not require a high level of integration.

VBAT is a complete constant-current/constant voltage linear charger for one cell lithium-ion battery. The charge current of pre-charging 

and constant–current charging is adjustable and it can be programmed to 700mA. An external resistor sets the charge current with 

high accuracy.VOUT1 and VOUT6 is a fixed-frequency, current-mode PWM step-down DC/DC converters that are optimized for 

high efficiency and is capable of supplying up to 500mA output current. VOUT2, VOUT3, VOUT4 and VOUT5 are low noise, high

 PSRR linear regulators

The CXLB7340 is available in a tiny 4mm × 4mm 24-pin Thin-QFN package that is just 0.75mm Height.
