SLUSDV8B November 2020 – March 2021 TPSM5D1806
PRODUCTION DATA
The TPSM5D1806 device is a dual output, step-down DC-DC power module with 4.5-V to 15-V input voltage range. Each device has two output channels and is capable of delivering up to 6-A of load current per channel. The device features exceptional efficiency and thermal performance in a very small solution size. The device is configurable as two independent 6-A outputs or a single 2-phase output to deliver up to 12 A. The TPSM5D1806 uses a fixed frequency, proprietary advanced current mode control architecture. The device operates in forced-PWM (FPWM) operation to maintain constant switching frequency over the load range. The device is internally compensated, which reduces design time and requires fewer external components. The switching frequency and the phase operation are configured using pin strapping. The MODE1 pin sets the phase operation. Table 7-4 shows the resistor values that are required to set the phase operation and the correct phase offset. The switching frequency can be selected from pre-set values of 500 kHz, 1.0 MHz, 1.5 MHz, and 2.0 MHz through pin-strapping on MODE2 pin. The TPSM5D1806 is also capable of synchronization to an external clock. The four switching frequency options allows the device to meet a wide range of design requirements. The module also features a power-good (PGOOD) flag for each channel, precision enable for each channel, internal or adjustable soft-start rate, and start-up into pre-bias voltage. The device has a pinout designed for simple, optimum PCB layout, low EMI, and excellent thermal performance.
