PAM2307

A Product Line of Diodes Incorporated PAM2307 3A LOW NOISE STEP-DOWN DC-DC CONVERTER 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 cell, multiple Alkaline/ 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 1µA. 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 42µA 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. Pin Assignments Features Output Current: Up to 3A Output Voltage: 0.6V to VIN Input Voltage: 2.7 to 5.5V Efficiency up to 95% 42µA (Typ) No Load Quiescent Current Shutdown Current: <1µA 100% Duty Cycle Operation 1.5M...
