Summary Specification
• Junction operating temperature -40 °C to 125 °C
• Packaged in a 16pin QFN (3x3)
Description
The TS51221 is a high-efficiency regulator device for low-
power wireless power receiver applications. The switching
frequency of 1MHz enables the use of small filter components
resulting in minimal board space and reduced BOM costs.
The TS51221 integrates a wide range of protection circuitry
including input supply under-voltage lockout, output voltage
soft start, current limit, and thermal shutdown.
Applications
• Wireless Charging for portable devices
• Wear-ables, medical monitors
• Bluetooth headsets
• Smart watches
