The TPS61388-Q1 is a 36V, 8A automotive fully-integrated synchronous boost converter with pass-through feature. The converter supports absmax voltage up to 40V while the max boost output voltage covers up to 30V.
The TPS61388-Q1 employs peak current mode control scheme with frequency options of 400kHz and 2.2MHz, and is capable of synchronized to an external clock. There are two optional modes at light load through MODE/SYNC pin configuring: Auto PFM mode and Forced PWM mode to balance the efficiency and noise immunity.
The device features low shutdown current and low quiescent current Pass-through operation, eliminates the need for an external bypass switch when the supply voltage is greater than output target.
The TPS61388-Q1 has various fixed output voltage versions to save the external components. TPS61388-Q1 supports the external loop compensation so that the stability and transient response is optimized.
The device has built-in protection features like peak current limit, overvoltage protection, and thermal shutdown. External clock synchronization, spread spectrum modulation, and a lead-less package with minimal parasitic help to reduce EMI. The TPS61388-Q1 is available in a 3.0mm × 2.5mm HotRod™ Lite WQFN package with wettable flank.
