GL5050 Datasheet | Gleam

Description The GL5050 are high-efficiency, CMOS, step-up, DC-DC switching regulators for small, low input volt-age or batterypowered systems. The GL5050 accept a positive input voltage between 0.9V and VOUT and convert it to a higher, pinselectable output voltage 5V. The GL5050 adjustable versions accept 0.9V to 5.0V input voltages. Typical efficiencies are greater than 80%. The GL5050 bine ultra-low quiescent supply current and high efficiency to give maximum battery life. An internal MOSFET power transistor permits high switching frequencies. This benefit, bined with internally set peak inductor current limits, permits the use of small, low-costinductors. The GL5050 have a 500m A peak inductor current limit.
