Product details
Overview
TPS65563ARGTR from Texas Instruments is an integrated photo flash charger and IGBT driver IC for xenon flash systems. It features a 50-V internal power switch (RON = 0.4–0.7 Ω), programmable primary-side peak current (0.5–2 A), and high-accuracy charge-complete detection (±0.8 V at VFULL). Designed for compact digital still cameras, it delivers fast capacitor charging with optimized PWM control and operates from 1.4–12 V battery input.
For engineers reviewing the TPS65563ARGTR datasheet, TPS65563ARGTR pinout, TPS65563ARGTR application, or TPS65563ARGTR equivalent, key selection criteria include primary-side peak current programming via I_PEAK voltage, SW terminal voltage rating (45 V max), thermal shutdown threshold (140–160°C), and dual-rail supply support (VCC: 2.7–5.5 V; IGBT_VCC: 2.7–5.5 V).
Technical Context
The TPS65563ARGTR implements a primary-side controlled flyback topology using internal comparators for zero-current detection (VZERO), charge-completion monitoring (VFULL), and peak-current limiting (IPEAK). Its integrated 50-V power switch enables direct transformer primary-side switching without external MOSFETs.
It integrates a dual-output IGBT gate driver (G_IGBT_P and G_IGBT_N) with independent turn-on/turn-off paths, supporting external IGBTs in xenon flash discharge circuits. Control logic synchronizes flash triggering only after XFULL asserts low - confirming full capacitor charge - and requires simultaneous assertion of F_EN and F_ON inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range (VBAT) | 1.4 V to 12 V - supports single-cell Li-ion up to 3-cell alkaline battery inputs without external regulation |
| Supply Voltage (VCC / IGBT_VCC) | 2.7 V to 5.5 V - dual independent rails enable flexible gate drive and logic supply partitioning |
| Peak Current Programming | 0.5 A to 2 A via I_PEAK pin voltage (0.1–1.5 V) - enables dynamic current scaling during charge cycle |
| SW Terminal Voltage Rating | 45 V max - sufficient for typical xenon flash transformer primary-side flyback spikes |
| Charge Completion Accuracy | ±0.8 V at VFULL - ensures reliable flash readiness detection across temperature and battery voltage |
| Thermal Shutdown Threshold | 140°C to 160°C - latches off operation to prevent die damage during sustained overload |
| Propagation Delay (tPD) | 25 ns to 200 µs - tight timing control for CHG-to-SW turn-on, F_ON-to-G_IGBT response, and XFULL assertion |
Pinout & Package
TPS65563ARGTR uses a 3-mm × 3-mm, 16-pin VQFN (RGT) package with exposed thermal pad (Pin 17), rated for –35°C to +85°C ambient operation. The PowerPAD™ enhances thermal dissipation and requires soldering to PCB ground plane per TI SLUA271 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pins 1, 2) | Power switch output | Drives transformer primary; handles up to 2.3 A peak current and 45 V flyback voltage |
| VBAT (Pin 3) | Battery monitor input | Detects battery voltage for OCP and timing; bypassed with 10-µF ceramic capacitor |
| I_PEAK (Pin 4) | Analog current setpoint | Voltage-controlled peak current reference (0.1–1.5 V → 0.5–2 A ISW) |
| CHG (Pin 6) | Charge enable input | Active-high latched control; low level resets XFULL and terminates charging |
| F_ON (Pin 7) | Flash trigger input | Enables IGBT firing only when F_EN is also high; controls xenon tube activation timing |
| F_EN (Pin 8) | Flash accept input | System-level permission signal; prevents flash if low, even if F_ON is high |
| XFULL (Pin 9) | Charge status output | Open-drain indicator; pulls low only after full-charge detection; high-Z during fault or charging |
| VCC (Pin 10) | Logic & gate drive supply | Powers internal circuitry and G_IGBT logic interface; bypassed with 1-µF ceramic capacitor |
| IGBT_VCC (Pin 11) | IGBT driver supply | Independent rail for G_IGBT_P/N outputs; decoupled separately for noise immunity |
| G_IGBT_P (Pin 12) | IGBT turn-on driver | Sources current from IGBT_VCC to IGBT gate; requires external series resistor |
| G_IGBT_N (Pin 13) | IGBT turn-off driver | Sinks current from IGBT gate to GND; matched impedance to G_IGBT_P for balanced switching |
| GND (Pins 5, 14, 15) | Power & signal ground | Common return for SW, VCC, IGBT_VCC, and analog comparators; must connect to solid ground plane |
| TEST_GND (Pin 16) | Factory test node | Internally connected to GND; must be tied to system ground on PCB |
Key Features
| Feature | Design Value |

| Dual-rail IGBT driver (G_IGBT_P/G_IGBT_N) | Provides matched turn-on/turn-off gate drive strength for robust xenon tube triggering without shoot-through risk |
| Overcurrent and thermal protection | Latched shutdown on SW overcurrent (VOCP = VBAT –100 mV) or junction temp >160°C ensures field reliability |
Applications
| Digital Still Cameras | Optical Film Cameras |
|---|---|
Use Scenario: Compact DSLR or mirrorless camera requiring rapid flash recharge between shots with minimal board area.

Equivalent & Alternatives
The following parts are listed as comparable options for similar photo flash charger and IGBT driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65561ARGTR | Lacks integrated IGBT driver; provides only flash charger function with SW and XFULL outputs | Requires external IGBT driver IC or discrete transistors for xenon tube control | Select when flash timing is managed externally and space permits separate driver stage |
| MAX16833AUB+ | Higher VSW rating (65 V); no integrated IGBT driver; uses external MOSFET and current-sense resistor | Targets automotive or industrial flash systems requiring extended voltage margin and design flexibility | Select when operating above 45 V SW stress or requiring programmable frequency/PWM slope control |
Compared with TPS65563ARGTR, TPS65561ARGTR reduces integration but increases BOM count and layout area, while MAX16833AUB+ trades compactness for higher voltage headroom and external component control - making TPS65563ARGTR optimal for space-constrained consumer imaging where full integration is prioritized.

FAQ
What is the maximum allowable voltage on the SW pin of the TPS65563ARGTR?
The TPS65563ARGTR specifies a maximum SW terminal voltage of 45 V under recommended operating conditions. Absolute maximum rating is 50 V, but sustained operation above 45 V risks overvoltage stress during flyback spikes. Designers must ensure transformer leakage inductance and snubber network limit VSW to ≤45 V during normal operation to maintain reliability and avoid triggering overcurrent protection.
How does the TPS65563ARGTR detect charge completion without secondary-side sensing?
The TPS65563ARGTR detects charge completion using primary-side voltage monitoring: the VFULL comparator monitors the SW node voltage relative to VBAT. When VSW exceeds VFULL (programmed as VBAT + 8.6–9.4 V), the device asserts XFULL low. This eliminates optocouplers or secondary-side resistive dividers, enabling compact isolated flyback designs while maintaining ±0.8 V detection accuracy across temperature.
Can the TPS65563ARGTR drive multiple xenon tubes simultaneously?
No - the TPS65563ARGTR integrates a single dual-output IGBT driver (G_IGBT_P and G_IGBT_N) designed for one external IGBT controlling one xenon tube. Driving multiple tubes would require separate IGBTs and duplicated driver stages, exceeding the IC's current capability and thermal limits. For multi-tube systems, parallel TPS65563ARGTR units or a higher-channel controller like TPS65562A are required.
What is the purpose of the TEST_GND pin on the TPS65563ARGTR?
The TEST_GND pin (Pin 16) is a factory test node internally connected to the main GND net. Texas Instruments uses it during wafer probe and final test. Per datasheet guidance, it must be connected to the system ground plane on the PCB - not left floating or tied to analog/digital ground splits - to ensure proper thermal conduction, EMI suppression, and functional stability of the exposed PowerPAD™ thermal pad.
Does the TPS65563ARGTR support automatic recharging after flash discharge?
Yes - the TPS65563ARGTR supports automatic recharging. After XFULL goes low (indicating full charge) and the host triggers flash via F_EN/F_ON, the device remains enabled. Once flash discharge completes and VSW drops, the internal control loop automatically resumes charging if CHG remains high. No external re-enable signal is needed, enabling rapid successive flash cycles in burst-mode photography.
