Product details
Overview
TPS922053DMTR from Texas Instruments is a 65V, 2A/4A non-synchronous buck LED driver with integrated 150mΩ low-side NMOS FET, 4.5–65V input range, and inductive fast dimming (IFD) capability. It supports analog, PWM, hybrid, and flexible dimming modes-including 150ns minimum PWM pulse width-and features spread spectrum EMI reduction. It is used in high-precision machine vision lighting and medical surgical illumination requiring stable current regulation and rapid brightness control.
For engineers reviewing the TPS922053DMTR datasheet, TPS922053DMTR pinout, TPS922053DMTR application, or TPS922053DMTR equivalent, this page delivers verified specifications, validated VSON-14 pin functions, real-world dimming performance data (e.g., 2,000:1 at 20kHz hybrid dimming), thermal foldback configuration, and direct comparisons to TPS922052DMTR and TPS922055DMTR for system-level selection.
Technical Context
The TPS922053DMTR implements adaptive off-time current mode control with configurable switching frequency (100kHz–2.2MHz via FSET resistor) and enabled spread spectrum (±7%, 2kHz modulation) to reduce EMI peaks. Its IFD architecture enables precise inductor-based current regulation during fast dimming transitions without external compensation loop redesign.
It integrates constant-current (CC) and constant-voltage (CV) control for dual-mode operation-driving LEDs in common-anode topology while supporting battery charging and TEC control. Protection includes cycle-by-cycle current limiting, LED open/short detection, thermal foldback (configurable via TEMP pin), and fault reporting via open-drain FAULT pin.

Pinout & Package
VSON-14 package (4.5mm × 3.0mm, 0.5mm pitch) with exposed thermal pad; optimized for single-layer PCB layout and high-power density LED driver designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND / AGND | Power & analog ground | Separate ground pins minimize noise coupling between power switching and feedback paths; thermal pad connects to both. |
| VIN | Main input supply | Accepts 4.5–65V; powers internal LDO and switching FET; UVLO threshold = 3.2V (rising). |
| VCC | Internal LDO output | 5.15V ±0.15V regulated supply for logic and gate drive; requires 1μF capacitor to AGND. |
| EN/PWM | Enable / PWM input | Pull-high for always-on; accepts 150ns PWM pulses; rising edge triggers soft-start after UVLO exit. |
| ADIM/HD | Analog dimming / hybrid dimming select | Pull-low enables hybrid dimming; PWM input enables analog dimming; configures dimming mode at startup. |
| FAULT | Fault indicator | Open-drain output pulled low on LED open/short, thermal shutdown, or current limit fault; requires pull-up resistor. |
| TEMP | Thermal foldback control | Resistor-to-AGND sets foldback curve; direct AGND connection disables foldback. |
| FSET | Frequency setting | Resistor-to-AGND selects 100kHz–2.2MHz; e.g., 59kΩ = 400kHz; enables EMI optimization. |
| COMP | Error amplifier output | Connects to external RC network; bandwidth and phase margin tuned via capacitor value. |
| CSP / CSN | Current sense inputs | Differential pair measuring voltage across external RSENSE; 200mV full-scale reference. |
| SW | Switching node | Drives external inductor and freewheeling diode; connects internally to low-side NMOS drain. |
| UVP | LED open detection | Resistor divider sets LED open threshold; floating disables UVP protection. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS922052DMTR | No spread spectrum; identical pinout, package, and 3A current limit. | Better suited for brightness-critical low-EMI-sensitive applications where spectral purity > EMI reduction. | Select when EMI filter size is not constrained and maximum dimming fidelity at low brightness is prioritized. |

FAQ
What dimming modes does the TPS922053DMTR support?
The TPS922053DMTR supports four distinct dimming modes: analog dimming (256:1), fast PWM dimming (150ns minimum pulse width), hybrid dimming (2,000:1 at 20kHz), and flexible dimming (1,000,000:1 at 120Hz). Mode selection is determined by logic states on the EN/PWM and ADIM/HD pins at startup, and all modes leverage the device's adaptive off-time current mode control for precise inductive fast dimming without output capacitor interference. Each mode is fully documented in the TPS922053DMTR datasheet Section 7.3.5.
Does the TPS922053DMTR include spread spectrum functionality?
Yes, the TPS922053DMTR has spread spectrum enabled by default - a key differentiator from the TPS922052DMTR. It modulates the switching frequency by ±7% at 2kHz to reduce EMI peak amplitudes, lowering conducted and radiated emissions without affecting regulation accuracy or dimming performance. This feature is factory-configured and cannot be disabled; it applies across the full 100kHz–2.2MHz frequency range set by the FSET resistor.
What is the maximum continuous output current of the TPS922053DMTR?
The TPS922053DMTR delivers up to 2A continuous LED current (with 4A peak capability) when configured with appropriate external components - including a properly rated inductor, Schottky diode, and current-sense resistor. Its integrated 150mΩ low-side NMOS FET and thermal design (RθJA = 39.1°C/W in VSON-14) enable this rating within the –40°C to +125°C junction temperature range, assuming adequate PCB copper area and airflow per TI's layout guidelines.
How is thermal foldback configured on the TPS922053DMTR?
Thermal foldback on the TPS922053DMTR is configured via the TEMP pin: connecting a resistor between TEMP and AGND sets the foldback curve's slope and onset temperature (default onset ~130°C with 20kΩ). Removing the resistor or shorting TEMP to AGND disables foldback entirely, leaving only hard thermal shutdown at 165°C. The foldback behavior is fully characterized in the TPS922053DMTR datasheet Figure 6-5 and Section 7.3.4, enabling predictable derating under sustained thermal stress.
Is the TPS922053DMTR pin-compatible with other devices in the TPS92205x family?
Yes - the TPS922053DMTR shares identical VSON-14 pinout, footprint, and signal mapping with TPS922052DMTR and TPS922054DMTR, enabling drop-in replacement for spread spectrum evaluation or current rating upgrades. However, functional differences exist: TPS922052DMTR lacks spread spectrum, and TPS922054DMTR supports 6A current limit without spread spectrum. Always verify FSET resistor, RSENSE, and thermal design against the target variant's electrical characteristics before substitution.
