The ADP1148 is a high efficiency synchronous step-down switching regulator with very low dropout operation and is suitable for use in notebook and palmtop computers, portable instruments, battery operated digital devices, industrial power distribution, avionics systems, telecom power supplies and GPS systems.
The ADP1148 family includes the adjustable ADP1148, as well as fixed output versions ADP1148-3.3 (3.3V) and ADP1148-5 (5V). These devices are synchronous step-down switching regulator controllers designed for high efficiency operation from 3.5 V to 18 V input voltages.
| Input Voltage Range | 3.5 V to 18 V |
|---|---|
| Maximum Efficiency | > 95% |
| Operating Temperature Range (Commercial) | 0°C to +70°C |
The devices drive external complementary power MOSFETs at switching frequencies up to 250 kHz.
The family includes an adjustable version and fixed versions for 3.3 V (ADP1148-3.3) and 5 V (ADP1148-5).
