YS05S16 DC-DC Converter Data Sheet3.0-5.5 VDC Input; 0.7525-3.63 VDC Programmable @ 16 AFig. 1.0V.5: Turn-on transient for Vout = 1.0 V with application ofVin at full rated load current (resistive) and 100 μF externalcapacitance at Vin = 5 V. Top trace: Vin (5 V/div.); Bottom trace:output voltage (1 V/div.); Time scale: 2 ms/div.Fig. 1.0V.6: Output voltage ripple (20 mV/div.) at full rated loadcurrent into a resistive load with external capacitance 100 μFceramic + 1 μF ceramic and Vin = 5 V for Vout = 1.0 V. Timescale: 2 μs/div.Fig. 1.0V.7: Output voltage response Vout = 1.0 V to positive loadcurrent step change from 8 A to 16 A with slew rate of 5 A/μs atVin = 5 V. Top trace: output voltage (100 mV/div.); Bottom trace:load current (5 A/div.). Co = 100 μF ceramic + 1 μF ceramic. Timescale: 20 μs/div.Fig. 1.0V.8: Output voltage response for Vout = 1.0 V to negativeload current step change from 16 A to 8 A with slew rate of -5 A/μsat Vin = 5 V. Top trace: output voltage (100 mV/div.); Bottomtrace: load current (5 A/div.). Co = 100 μF ceramic + 1 μFceramic. Time scale: 20 μs/div.MCD10205 Rev. 1.0, 24-Jun-10 Page 22 of 25 www.power-one.com
