- 0.5-V to 5.5-V output voltage range
- Four selectable PWM ramp options for each switching frequency to optimize control loop performance
- Soft start time is configurable by an external cap in single-output, multi-phase configuration and is fixed at 1 ms for dual-output configuration
- True differential remote sensing in multi-phase operation
- Independent enable and power good
- Four selectable switching frequency options of 500 kHz, 1 MHz, 1.5 MHz, and 2.0 MHz
- Supports safe pre-biased start-up
- Overtemperature protection with hysteresis
- –40°C to 150°C operation junction temperature
- 3-mm × 5-mm, 25-pin VQFN-HR package with 0.5-mm pitch
The TPS541620 is a highly integrated non-isolated dual DC-DC converter that is capable of high-frequency operation in a 3-mm × 5-mm package. The device can be configured as two single 6-A rails or combined to drive a single 12-A current load. The device implements a fixed-frequency advanced current mode control (ACM) with selectable ramp amplitude configurations to optimize the loop bandwidth. Two mode selection pins (MODE1 and 2) are used to select switching frequency, configuration, clock phase delay, and internal compensation.
