The ADPL20502® is a boost converter capable of delivering a peak inductor current up to 2A with True Shutdown™, cycle-by-cycle inductor current limit, short circuit, and thermal protection. During shutdown, only 1nA is drawn from the input pin. The ADPL20502 offers ultra-low quiescent current, small total solution size, and operates at a high efficiency throughout the load and line range. The ADPL20502 is ideal for batterypowered applications where long battery life is a must and high efficiency is required at all power levels.
The ADPL20502 utilizes an adjustable on-time, pulsefrequency modulation (PFM) control scheme that consumes ultra-low quiescent current. The ADPL20502 features True Shutdown mode where the output disconnects from the input with no forward or reversecurrent. This saves precious energy from the battery for systems that dynamically turn on and off by having the ability to startup into a precharged output capacitor.
The ADPL20502 is offered in a space-saving and cost effective 1.58mm x 0.89mm, 6-bump WLP (3 x 2, 0.4mm pitch) and 8-pin, 2mm x 2mm TDFN packages. The operating temperature range is from -40°C to +125°C.
