Product Overview
TPS61170 is a Texas Instruments high-voltage boost converter for Power_Management designs requiring step-up conversion from a recommended 3 to 18 V input range. Its recommended output range is VIN to 38 V, and it integrates a 40-V power MOSFET with a 1.2-A switch current rating.
The converter uses a fixed PWM switching frequency of 1.2 MHz typical, with an oscillator range of 1.0 to 1.5 MHz under the stated VIN, CTRL, and temperature conditions. Feedback regulation is based on a 1.229 V typical reference, with a 492 mV typical reprogrammed feedback voltage mode.
TPS61170 is supplied in a compact 6-pin VSON/QFN package measuring 2.00 mm x 2.00 mm. Recommended external components include a 10 to 22 uH inductor, 1 uF input capacitor, and 1 to 10 uF output capacitor. Thermal data for the DRV 6-pin package includes 66.5 °C/W junction-to-ambient resistance and 7.1 °C/W junction-to-case bottom resistance.
