SLVUCQ6 july 2023 TPS7H2211-SEP
If a custom configuration is desired, then users need to refer to the TPS7H2211 data sheet to calculate the values of the passive components around the device and note any operational requirements.
In addition to the default EVM configuration, this user's guide provides an example for how the TPS7H2211EVM can be configured for parallel operation. The enable (EN) and overvoltage protection (OVP) specifications for the parallel configuration are the same as what is used for the default configuration. However, this configuration is capable of providing up to double the output current compared to the default configuration.
| Specification | Value | Description |
|---|---|---|
| Input Voltage VIN | 13 V | Falls within the recommended device input voltage range of 4.5 to 14 V. |
| Output Current IOUT | 0 to 7 A | Does not exceed maximum device continuous current of 3.5 A per device. |
| EN Turn-on Voltage VINEN_RISE | 7.4 V | Typical EN turn-on and turn-off values. Set by: R3 (RTOP_EN) = 100 kΩ R4 (RBOT_EN) = 9.31 kΩ R15 populated |
| EN Turn-off Voltage VINEN_FALL | 6.1 V | |
| OVP Enter Voltage VINOVP_RISE | 13.5 V | Typical OVP enter and exit values. Set by: R2 (RTOP_OVP) = 100 kΩ R5 (RBOT_OVP) = 9.31 kΩ R17 populated |
| OVP Exit Voltage VINOVP_FALL | 13.4 V | |
| Soft Start Time tSS | approx. 10.9 ms | Typical time to go from 10% to 90% of the final voltage. Set by: C13 (CSS) = 68 nF C28 (CSS) = 68 nF R16 populated |
More detailed information about the parallel EVM configuration can be found in Figure 5-2 and Table 5-2.
