In this case, the device starts 100% duty cycle operation turning on the high-side switch 100% of the time. The high-side switch stays turned on as long as the output voltage is below the internal setpoint.

TPS62160 TPS62161, TPS62162, TPS62163 SLVSAM2C – NOVEMBER 2011 – REVISED SEPTEMBER 2013 www.ti.com The dynamic high side switch peak current can be calculated as follows: I peak ( typ ) = I LIMF _ HS + (V IN - VOUT ) × 30ns L (5) Care on the current limit has to be taken if the input voltage is high and very small inductances are used. Power Good (PG) The TPS6216X has a built in power good (PG) function to indicate whether the output voltage has reached its appropriate level or not.

Programming The Output Voltage While the output voltage of the TPS62160 is adjustable, the TPS62161/2/3 are programmed to fixed output voltages. For fixed output versions, the FB pin is pulled down internally and may be left floating.

Calculating the maximum inductor current using the actual operating conditions gives the minimum saturation current of the inductor needed. A margin of about 20% is recommended to add.

TPS62160 TPS62161, TPS62162, TPS62163 www.ti.com SLVSAM2C – NOVEMBER 2011 – REVISED SEPTEMBER 2013 NOTE DC Bias effect: High capacitance ceramic capacitors have a DC Bias effect, which will have a strong influence on the final effective capacitance. Therefore the right capacitor value has to be chosen carefully. Package size and voltage rating in combination with dielectric material are responsible for differences between the rated capacitor value and the effective capacitance.

TPS62160 TPS62161, TPS62162, TPS62163 SLVSAM2C – NOVEMBER 2011 – REVISED SEPTEMBER 2013 www.ti.com In summary, the input capacitor should be placed as close as possible to the VIN and PGND pin of the IC. This connections should be done with wide and short traces. The output capacitor should be placed such that its ground is as close as possible to the IC's PGND pins - avoiding additional voltage drop in traces. This connection should also be made short and wide.

TPS62160 TPS62161, TPS62162, TPS62163 www.ti.com SLVSAM2C – NOVEMBER 2011 – REVISED SEPTEMBER 2013 The TPS6216X is designed for a maximum operating junction temperature (Tj) of 125°C. Therefore the maximum output power is limited by the power losses that can be dissipated over the actual thermal resistance, given by the package and the surrounding PCB structures.
