Power Management GL5050
500mA 500KHz DC-DC CONVERTOR BOOST REGULATOR
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 combine ultra-low quiescent suppl.

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 combine ultra-low quiescent supply current and high efficiency to give maximum battery life. An internal MOSFET power transistor permits high switching frequencies. This benefit, combined with internally set peak inductor current limits, permits the use of small, low-costinductors. The GL5050 have a 500mA peak inductor current limit.
