PAM2306D

Green PAM2306D DUAL HIGH-EFFICIENCY PWM STEP-DOWN DC-DC CONVERTER Description The PAM2306D is a dual step-down current mode, DC-DC converter. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the PAM2306D provides a powersaving Pulse-Skipping Modulation (PSM) mode to reduce quiescent current under light load operation. Pin Assignments The PAM2306D supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH cell, USB, and other standard power sources. The dual output voltages are available for adjustment. All versions employ 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 0.1µA. Other key features include under-voltage lockout to prevent deep battery discharge. Features Efficiency up to 96% Only 40μA (Typ per Channel) Quiescent Current Output Current: Up to 1A per Channel Internal Synchronous Rectifier 1.5MHz Switching Frequency Soft-Start Under-Voltage Lockout Short Circuit Protection Thermal Shutdown Small 12L WDFN3x3 Package Lead-Free Finish; RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC...
