TPSM81299 Description
The TPSM81299 is a synchronous boost module, with inductor and converter both incorporated inside, providing 95nA ultra-low quiescent current and average input current limit. The device provides a power product for portable equipment with alkaline battery and coin cell battery.
TPSM81299 Key Features
- Input voltage range: 0.5V to 5.5V
- 0.7V minimum start-up voltage
- Input operating voltage (PVIN) down to 150mV
- Average input current limit: 5mA; 25mA; 50mA
- 95nA typical quiescent current into VOUT
- 60nA 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 =200mA
- Fast transient performance: setting time ~8μs at PVIN=AVIN = 3.6V, VOUT = 5V, IOUT = 0A -> 200mA
- True disconnection at EN low
