TPS61088-Q110-A fully-integrated synchronous boost converter, AEC-Q100 qualified | DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards | 4 | Active | The TPS61088-Q1 is a 2.7-V to 12-VINhigh power density, synchronous boost converter designed to provide a high-efficiency, small-size solution for automotive applications. The TPS61088-Q1 has a minimum input voltage of 2.7 V and therefore can act as a boost for a single or two cell Li-Ion back-up battery (BUB) in applications such as E-Call that also require a high power output to drive the speaker, antenna, and other circuits.
The device can also be used as a post-boost, boosting from the main automotive system 3.3-V rail to power CAN transceivers and other circuits requiring 5 V.
The 12.6-VOUTcapability allows the TPS61088-Q1 to also power audio amplifiers (for example, 10 V or 11 V for E-Call), antenna, power-over-coax (PoC), and automotive audio bus (A2B) devices.
The 10-A switch current enables applications that require operation during cold crank, for example, at 3.5 VINto 11 VOUTwhile still delivering up to 2-A load current.
The TPS61088-Q1 uses adaptive constant off-time peak-current-control topology to regulate the output voltage. In moderate-to-heavy load condition, the TPS61088-Q1 works in the pulse width modulation (PWM) mode. In light load condition, the device has two operation modes selected by the MODE pin. One is the pulse frequency modulation (PFM) mode to improve the efficiency and another one is the forced PWM mode to avoid application problems caused by low switching frequency. The switching frequency in the PWM mode is adjustable ranging from 200 kHz to 2.2 MHz by an external resistor. The TPS61088-Q1 also implements a programmable soft-start function and an adjustable switching peak-current-limit function. In addition, the device provides 13.2-V output overvoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown protection.
The TPS61088-Q1 is available in a 4.50-mm × 3.50-mm 20-pin VQFN package.
