The IC has four power domains:
The AT5830 can be operated from V
5.5V (5V application). For TX output powers above 10dBm applied in high band frequency
ranges 836MHz to 928MHz, the minimum battery voltage is limited to 2.1V.
• VS – The unregulated battery voltage input.
• DVCC – The internally regulated digital supply voltage. Typical value is 1.35V.
• AVCC – The internally regulated RF frontend and XTO supply. Typical value is 1.85V.
• VS_PA – The power amplifier supply has two application modes depending on the battery
voltage (VS) range:
– Connected externally to the battery in 3V applications.
– Generated by an internal regulator in 5V applications.
