TPS61170DRVR

TPS61170DRVR is the tape-and-reel WSON-6 (DRV, 2 mm by 2 mm) ordering code for the Texas Instruments TPS61170 boost converter, listed by TI as ACTIVE. It accepts a 3 V to 18 V input, regulates outputs up to 38 V through an integrated 40 V MOSFET with a typical 1.2 A switch current limit, switches at a fixed 1.2 MHz against a 1.229 V feedback reference, draws 2.3 mA typical quiescent current, reaches a maximum duty cycle of 93 % and is characterised at up to 93 % efficiency. The selection point is a high-voltage bias rail from a low-voltage input in a two-square-millimetre package: OLED and LED bias, piezo drivers and sensor supplies get a documented 38 V boost without an external switch. Selection advice: the 38 V output figure sits below the 40 V switch rating - design the output target and transient overshoot with margin under the switch limit, and budget load current from the switch limit at the actual input voltage rather than the headline efficiency point. Parameters verified against the TI TPS61170 datasheet (Rev. D) and the TI ordering page for this code.
