Product details
Overview
TLE63892GV50XUMA1 from Infineon Technologies is a fixed 5V step-down DC/DC controller driving an external P-channel MOSFET, supporting input voltages up to 60V, delivering up to 2.3A output current, featuring 360kHz fixed switching frequency, integrated undervoltage reset with 50mV hysteresis, and AEC-Q100 qualification for automotive power supply rails.
For engineers reviewing the TLE63892GV50XUMA1 datasheet, TLE63892GV50XUMA1 pinout, TLE63892GV50XUMA1 application, or TLE63892GV50XUMA1 equivalent, key selection criteria include its 5V fixed output accuracy (±3%), 120µA light-load quiescent current, 2µA shutdown current, RO/SO open-drain outputs with internal 20kΩ pull-up to VOUT, and PG-DSO-14-1 package compatibility with high-temperature automotive environments.
Technical Context
The TLE63892GV50XUMA1 implements a current-mode PWM/PFM hybrid control scheme enabling 100% duty cycle operation for ultra-low dropout, eliminating minimum load requirements while maintaining regulation down to 1mA. Its internal low-battery comparator (SI input referenced to 1.25V) and undervoltage reset circuit (RO threshold 4.5–4.8V) operate independently of the main regulator loop.
It integrates a clamped gate-drive supply (BDS–VS capacitor), GDRV output swinging between VS and BDS levels, and CS-based peak-current sensing with external sense resistor. The fixed 5V version internally connects FB to a precision voltage divider, removing need for external feedback resistors.

Pinout & Package
Package: PG-DSO-14-1 (14-pin plastic dual small outline, exposed thermal pad, RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SI_ENABLE | Active-high enable for SI_GND switch | Controls low-impedance connection of SI_GND to GND; SO/RO undefined when low |
| 2 FB | Feedback reference input | Internally tied to 5V divider; no external connection required for fixed-output operation |
| 3 VOUT | Buck output voltage sense | Provides internal bias supply; must connect directly to output capacitor node |
| 4 GND | Analog ground reference | Primary signal return for FB, COMP, CS, and internal comparators |
| 5 SYNC | External clock synchronization input | Accepts 360kHz ±15% external clock to phase-align multiple controllers |
| 6 SI_GND | Low-battery comparator ground | Switched to GND via SI_ENABLE; forms reference leg for SI voltage divider |
| 7 SI | Sense comparator input | Compares external voltage against 1.25V internal reference; drives SO open-drain output |
| 8 COMP | Control loop compensation node | Connects RC network to GND to stabilize current-mode control loop dynamics |
| 9 SO | Sense comparator output | Open-drain output pulled up to VOUT via 20kΩ; asserts low when SI < 1.25V |
| 10 RO | Undervoltage reset output | Open-drain output pulled up to VOUT via 20kΩ; asserts low when VOUT < 4.5V |
| 11 BDS | Buck driver supply | Forms floating supply for GDRV; requires ceramic cap between BDS and VS |
| 12 GDRV | Gate drive output | Drives P-MOSFET gate between VS and BDS levels; supports fast turn-on/turn-off |
| 13 VS | Main device supply | Input rail connection; requires 220nF ceramic + low-ESR tantalum bulk capacitance |
| 14 CS | Current sense input | Monitors voltage drop across external sense resistor (e.g., 47mΩ); triggers MOSFET turn-off at peak current |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Operation | Enables regulation down to VIN − VOUT ≈ 0.3V, critical for cold-crank automotive scenarios |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down DC/DC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569DRVR | 3.3V–18V input, 5V fixed output, 2A max, 2.5MHz switching, no RO/SO, no SI comparator | Lacks automotive temp range, reset, and battery sense; suited for consumer-grade portable devices | Select only if AEC-Q100, RO, or SI functionality is unnecessary and higher frequency is preferred |
| MAX16922ATP+T | 4.5V–28V input, 5V fixed output, 2.5A max, 2.2MHz, integrated FET, no SI/RO hysteresis | Includes internal MOSFET but lacks programmable hysteresis and dedicated low-battery comparator | Choose when board space is constrained and external MOSFET drive is not required |
Compared with TLV62569DRVR and MAX16922ATP+T, TLE63892GV50XUMA1 uniquely combines AEC-Q100 Grade 0 qualification, dual comparator outputs (RO/SO) with configurable hysteresis, and external P-MOSFET drive flexibility-making it irreplaceable for safety-critical automotive power rails requiring robust brownout and battery monitoring.

FAQ
What is the function of the SI_ENABLE pin on TLE63892GV50XUMA1?
The SI_ENABLE pin controls the internal switch connecting SI_GND to GND. When high, SI_GND is low-impedance to GND, enabling proper operation of the SI comparator. When low, SI_GND floats, and SO/RO outputs become undefined. It does not disable the main regulator-only the SI comparator path.
Can TLE63892GV50XUMA1 be used with an N-channel MOSFET instead of a P-channel?
No. TLE63892GV50XUMA1 is designed exclusively for external P-channel MOSFETs, as its GDRV output swings between VS and BDS to provide proper gate-source voltage control. Using an N-channel MOSFET would require high-side gate drive with level-shifting, which this controller does not support.
How does the RO output behave during power-up and brownout conditions?
RO is an open-drain output pulled up to VOUT via an internal 20kΩ resistor. It remains high until VOUT drops below 4.5V, then pulls low. After recovery, it releases only when VOUT exceeds 4.8V due to 50mV hysteresis-preventing oscillation during slow voltage ramp-up or noise-induced dips.
Is external compensation required on the COMP pin, and what topology is recommended?
Yes, external RC compensation is mandatory on COMP to stabilize the current-mode control loop. A Type II compensator (series RC from COMP to GND, with optional capacitor across R) is recommended. Component values depend on inductor value, output capacitance, and desired phase margin-design guidance is provided in Infineon's TLE6389 application note AN2007-08.
