Charge pump, 5V fixed at 30mA
The LTC1928ES6-5#TRMPBF is a step-up charge pump from Analog Devices delivering a fixed 5V output at up to 30mA. Switching at 550kHz, it generates a positive regulated rail from a 2.7V to 4.4V input — suitable for battery-powered or low-voltage bus applications that need a clean 5V supply without an inductor.
TSOT-23-6 package and board-fit
Housed in a 6-lead TSOT-23-6 (SOT-23-6 Thin) package, this part is a surface-mount charge pump with a small footprint — the 0.95mm pitch and low profile suit dense PCB layouts where height is constrained.
Temperature grade and operating environment
The charge pump topology does not use a synchronous rectifier, so the 30mA output current is the practical ceiling for continuous operation within this temperature envelope.
