Device Description A. General MAX38650 is a nanoPower ultra-low 390nA quiescent current buck (step-down) DC-DC converter operating from 1.8V to 5.5V input voltage and supporting load currents of up to 100mA with peak efficiencies of 95%. While in shutdown, there is only 5nA of shutdown current. The device offers ultra-low quiescent current, small total solution size, and high efficiency throughout the load range. The device is ideal for battery applications where long battery life is a must. MAX38650 supports 100% Duty Cycle operation allowing seamless transition as battery discharges and falls below the target output voltage.MAX38650 utilizes a unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range. The device is offered in a spacesaving 1.58mm x 0.89mm 6-pin wafer-level package (WLP) (2 x 3 bumps, 0.4mm pitch)The part is specified for operating temperature from -40°C to +125°C.

Reliability Evaluation A. Accelerated Life Test The results of the 125C biased (static) life test are shown in Table 1. Using these results, the Failure Rate 𝜆= 1 𝑀𝑇𝑇𝐹 = is calculated as follows: 1.83 (Chi square value for MTTF upper limit) 192 𝑥 2454 𝑥 80 𝑥 2 (where 2454 = Temperature Acceleration factor assuming an activation energy of 0.8eV) 𝜆 = 24.3 𝑥 10−9 𝜆 = 24.3 𝐹𝐼𝑇𝑠 (60% 𝑐𝑜𝑛𝑓𝑖𝑑𝑒𝑛𝑐𝑒 𝑙𝑒𝑣𝑒𝑙 @25°𝐶) Maxim Integrated performs quarterly life test monitors on its processes. This data is published in the Reliability Report found at https://www.maximintegrated.com/en/support/qa-reliability/reliability/reliability-monitor-program.html. S18 cumulative process Fit 𝜆 = 0.02 𝐹𝐼𝑇𝑠 (60% 𝑐𝑜𝑛𝑓𝑖𝑑𝑒𝑛𝑐𝑒 𝑙𝑒𝑣𝑒𝑙 @25°𝐶) 𝜆 = 0.24 𝐹𝐼𝑇𝑠 (60% 𝑐𝑜𝑛𝑓𝑖𝑑𝑒𝑛𝑐𝑒 𝑙𝑒𝑣𝑒𝑙 @55°𝐶) B. ESD and Latch-Up Testing The MAX38650 has been found to have all pins able to withstand an HBM transient pulse of ±2500 V per JEDEC / ESDA JS-001. Latch-Up testing has shown that this device withstands ±250 mA current injection and supply overvoltage per JEDEC JESD78. Maxim Integrated. All rights reserved.
