Product details
Overview
TPS54160ADGQ from Texas Instruments is a 60-V, 1.5-A synchronous step-down DC/DC converter with integrated 200-mΩ high-side MOSFET, Eco-mode™ pulse-skipping for 116-μA quiescent current, and adjustable 100-kHz to 2.5-MHz switching frequency. It delivers regulated 3.3-V output at up to 1.5 A in industrial power supplies requiring wide VIN (3.5–60 V) and high light-load efficiency.
For engineers reviewing the TPS54160ADGQ datasheet, TPS54160ADGQ pinout, TPS54160ADGQ application, or TPS54160ADGQ equivalent, key selection criteria include its tighter enable threshold (1.11–1.36 V vs. TPS54160's 0.9–1.55 V), boot UVLO protection, PWRGD open-drain monitoring, and MSOP-10 package with exposed thermal pad for thermal management.
Technical Context
The TPS54160ADGQ implements constant-frequency peak current-mode control with internal slope compensation to prevent subharmonic oscillation across duty cycles. Its error amplifier (26 μ℧ transconductance during slow start, 97 μ℧ typical) drives COMP to regulate VSENSE against a 0.8-V reference with ±1.6-mV accuracy over temperature.
It integrates boot recharge diode and boot UVLO circuitry that disables the high-side MOSFET if BOOT–PH falls below 2.1 V, enabling reliable 100% duty-cycle operation. The RT/CLK pin supports both resistor-set frequency tuning and external clock synchronization via PLL lock-in (100-μs lock time).

FAQ
What is the minimum input voltage required for TPS54160ADGQ to start switching?
The TPS54160ADGQ has an internal undervoltage lockout threshold of 2.5 V, but startup occurs when VIN exceeds the adjusted enable threshold. With EN floating, the device starts when VIN rises above ~2.5 V. When EN is biased externally, startup voltage depends on the resistor divider - for example, with R1=100 kΩ and R2=49.9 kΩ from VIN to EN to GND, startup occurs at ~7.7 V (rising) and hold-off at ~6.7 V (falling). This behavior is confirmed in Section 7.5 of the TPS54160ADGQ datasheet.
Does TPS54160ADGQ support synchronization to an external clock signal?
Yes, the TPS54160ADGQ supports external clock synchronization via the RT/CLK pin. When the pin voltage exceeds 1.9 V, the internal oscillator amplifier disables and the pin becomes a high-impedance clock input to the internal PLL. It accepts clock frequencies from 300 kHz to 2.2 MHz, with PLL lock-in time of 100 μs. This feature enables noise-sensitive systems to align switching edges and reduce EMI peaks - a capability verified in the Functional Block Diagram and Electrical Characteristics tables of the official TPS54160ADGQ datasheet.
How does the PWRGD pin of TPS54160ADGQ behave during output overvoltage conditions?
The PWRGD pin of TPS54160ADGQ asserts low when VSENSE falls below 94% or rises above 107% of the nominal output voltage. During overvoltage, the OV comparator triggers, turning off the high-side MOSFET and holding it off until VSENSE drops below 107%. This causes PWRGD to remain low until regulation is restored. The pin is open-drain and requires an external pull-up resistor. This dual-threshold behavior is explicitly defined in Section 7.5 (Electrical Characteristics) and Figure 21 of the TPS54160ADGQ datasheet.
Can TPS54160ADGQ operate with 100% duty cycle, and what condition enables it?
Yes, the TPS54160ADGQ supports 100% duty cycle operation as long as the BOOT–PH voltage remains above 2.1 V. This is enforced by the internal boot UVLO circuit, which disables the high-side MOSFET if BOOT–PH drops below this threshold. The integrated boot recharge diode and recommended 0.1-μF X7R ceramic capacitor ensure reliable boot capacitor refresh even at high duty cycles. This capability is documented in Section 8.1 (Overview) and Feature Description subsection 8.3.4 of the TPS54160ADGQ datasheet.
What is the purpose of the SS/TR pin on TPS54160ADGQ, and how is it used during fault recovery?
The SS/TR pin on TPS54160ADGQ controls output voltage ramp rate (slow start) or tracks another supply (sequencing). During overload, thermal shutdown, or EN-disable events, the internal overload recovery circuit actively discharges the SS/TR capacitor to 0 V, ensuring consistent restart behavior. Upon fault removal, the capacitor recharges from zero, initiating a controlled soft-start from the fault voltage level back to regulation. This behavior is detailed in Section 8.1 and Figure 26 (Pulse Skip Mode Operation) of the TPS54160ADGQ datasheet.
