PAM2307  3A低噪音同步降压DC-DC

PAM2307 Description
The PAM2307 is a 3A step-down DC-DC converter. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. No external compensation components are required The PAM2307 supports a range of input voltages from 2.7V to 5.5V, allowing the use of a single Li+/Li -polymer cel l , mul tiple Alkal ine/NiMH cell,and other standard power sources. The output voltage is adjustable from 0.6V to the input voltage. The PAM2307 employs internal power switch and synchronous rectifier to minimize external part count and realize high efficiency.
During shutdown, the input is disconnected from the output and the shutdown current is less than 1 A. Other key features include over-temperature and short circuit protection, and under-voltage lockout to prevent deep battery discharge. The PAM2307 delivers 3A maximum output current while consuming only 42 A of no-load quiescent current. Ultra-low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the PAM2307  an ideal choice for high output  voltage, high current applications which require a low dropout threshold.The PAM2307 is available in QFN3x3 16-Pin and SOP-8(EP) package.
