TPSM81299
Features
- Input voltage range: 0.5V to 5.5V
- 0.7V minimum start-up voltage
- Input operating voltage (PVIN) down to 150m V with signal AVIN > 0.7V
- Output voltage range: 1.8V to 5.5V for device with input current limit no more than 1.2A
- Average input current limit: 5m A; 25m A; 50m A;
100m A; 250m A, 500m A, 1.2A, 1.5A (different versions)
- 95n A typical quiescent current into VOUT
- 60n A typical shutdown current into AVIN
- Up to 88% efficiency at PVIN =AVIN=3.6V, VOUT = 5V, and IOUT =10μA
- Up to 94% efficiency at PVIN=AVIN = 3.6V, VOUT = 5V, and IOUT =200m A
- Fast transient performance: setting time ~8μs at PVIN=AVIN = 3.6V, VOUT = 5V, IOUT = 0A -> 200m A
- True disconnection at EN low
- Automatic PFM/PWM mode transition
- Auto pass-through at AVIN > VOUT
- Output SCP and thermal shutdown protections
- QFN package (3mm x 2.7mm x 1.27mm)
