The recommended input capacitor value is 10uF to 22uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize input voltage ripple.
To minimize noise and EMI, it is recommended to follow a star-ground configuration, keep the input and output capacitors close to the device, and use a solid ground plane. Additionally, avoid routing sensitive signals near the inductor and ensure that the layout is symmetrical to reduce radiation.
The maximum ambient temperature range for the TPS61002DGSR is -40°C to 125°C. However, the device's performance and reliability may be affected at extreme temperatures, so it is recommended to operate within a range of -20°C to 85°C for optimal performance.
Yes, the TPS61002DGSR is suitable for battery-powered devices due to its low quiescent current (IQ) of 12uA, which helps to extend battery life. However, it is essential to consider the device's power consumption and battery life requirements when designing the system.
The output voltage of the TPS61002DGSR can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.21V), and R1 and R2 are the resistors connected to the FB pin. The recommended values for R1 and R2 are 10kΩ and 2.2kΩ, respectively, which result in an output voltage of 3.3V.
