DC/DC converter measurement results
New recommended components yield results much closer to datasheet expectations
Much lower ripple when current draw is 10x lower than typical radio current; good news for timer stability
Large cap on battery side (DCDC input) will be necessary when using DCDC with high source resistances, e.g., printed batteries
Printed battery to DCDC to SCuM tests
Planning to revise method of battery current measurement
Expected 16 hr battery life; tested approx 10 hrs w/ inefficient DCDC component choice
