Product details
Overview
TPS65562RGTR from Texas Instruments is an integrated photo flash charger and IGBT driver IC for xenon flash applications. It combines a 50-V integrated power switch, programmable peak current control (0.9–1.8 A), primary-side output voltage feedback, thermal shutdown (160°C), and overcurrent protection (OVDS) in a single 16-pin QFN package. It operates from 1.6 V to 12 V battery input and delivers fast, high-efficiency flash capacitor charging for digital still cameras.
For engineers reviewing the TPS65562RGTR datasheet, TPS65562RGTR pinout, TPS65562RGTR application, or TPS65562RGTR equivalent, this device is selected for compact, high-reliability xenon flash systems requiring precise peak current programming, charge completion indication (XFULL), and isolated IGBT gate drive with dedicated IGBT_VCC supply.
Technical Context
The TPS65562RGTR implements a PWM-based flyback controller with internal 50-V power switch and analog peak current sensing via the I_PEAK pin. Its control loop uses zero-current detection (VZERO threshold at 1–60 mV) and full-charge detection (VFULL = 28.6–29.4 V) to regulate charge cycles without secondary-side feedback.
It integrates dual-domain power management: VCC (2.7–4.0 V) powers logic and switching circuitry, while IGBT_VCC (2.7–5.5 V) independently supplies the G_IGBT gate driver output. Protection includes MAX ON time (50–160 μs), MAX OFF time (25–80 μs), OVDS (0.95–1.45 V at SW), and thermal disable at 160°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VBAT = 1.6 V to 12 V - supports single-cell Li-ion up to multi-cell alkaline inputs without external regulators. |
| Peak Switch Current | IPEAK = 0.7–1.78 A - programmable via analog voltage on I_PEAK pin (0–3 V), enabling adaptive charging based on battery state. |
| Charge Completion Threshold | VFULL = 28.6–29.4 V - accurate primary-side detection eliminates optocoupler or secondary winding, reducing BOM count. |
| Switch ON Resistance | RONSW = 0.4–0.9 Ω - low RDS(on) minimizes conduction loss during high-current flyback charging phase. |
| Thermal Shutdown | TSD = 150–170°C - latch-off behavior prevents thermal runaway during sustained high-power flash operation. |
| Overcurrent Detection | OVDS = 0.95–1.45 V at SW - monitors VDS across internal switch to detect short-circuit or transformer saturation faults. |
| Package | 16-pin QFN (RGT), 3 mm × 3 mm - thermally enhanced PowerPAD™ design supports 1.16 W dissipation at 70°C ambient. |
Pinout & Package
TPS65562RGTR is housed in a 3 mm × 3 mm, 16-pin QFN package with exposed thermal pad (PowerPAD™). Pin 1 is top-left corner (marked dot), pins numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pins 1, 2) | Switch Output | Drives primary side of flyback transformer; rated for 50 V max and 2 A continuous; connects directly to transformer primary and PGND return path. |
| VCC (Pin 3) | Logic Supply Input | Powers internal control logic and PWM circuitry; requires 2.7–4.0 V; bypassed with 1 μF ceramic capacitor near pin. |
| F_ON (Pin 4) | Flash Discharge Trigger Input | Active-high logic input that enables G_IGBT when CHG = L; synchronizes xenon tube firing with charge completion. |
| I_PEAK (Pin 5) | Peak Current Programming Input | Analog input (0–3 V) setting ISW peak limit; thresholds defined at VPKL = 0.6 V (low) and VPKH = 2.4 V (high). |
| G_IGBT (Pin 6) | IGBT Gate Driver Output | Push-pull output swinging from PGND to IGBT_VCC; drives external IGBT gate with 8–70 Ω pull-up/pull-down resistance. |
| IGBT_VCC (Pin 8) | IGBT Driver Supply | Dedicated 2.7–5.5 V supply isolates gate drive from logic domain, preventing noise coupling and ensuring robust turn-on. |
| XFULL (Pin 9) | Charge Completion Indicator | Open-drain output pulled low when V(SW) ≥ VFULL; used with external pull-up to signal full charge to host controller. |
| CHG (Pin 10) | Charge Enable Input | Active-high logic input initiating charging cycle; latched internally; falling edge terminates charge immediately. |
| PGND (Pins 11, 12) | Power Ground | Main current return path for SW and internal switch; must connect to low-impedance ground plane under PowerPAD™. |
| TEST_GND (Pin 14) | Test Ground | Factory test node; electrically tied to PGND; must be connected to system ground plane in production layout. |
| VBAT (Pin 15) | Battery Input | Main power input (1.6–12 V); accepts wide battery range; requires 10 μF + 1 μF ceramic decoupling per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 50-V Power Switch | Eliminates external MOSFET, reduces PCB area by >30%, and removes gate drive design complexity for flyback topology. |
| Primary-Side Voltage Feedback (VFULL) | Enables accurate 29 V ±0.2 V charge termination without secondary-side components, improving reliability and cost. |
| Programmable Peak Current (I_PEAK) | Supports dynamic adaptation: higher current for full batteries (1.78 A), lower for depleted cells (0.7 A), extending usable battery life. |
| Dual Independent Supplies (VCC & IGBT_VCC) | Prevents logic noise from modulating gate drive strength; allows optimized IGBT_VCC selection (e.g., 5 V) independent of 3.3 V logic rail. |
| Zero-Current Detection (VZERO) | Triggers switch reactivation at <60 mV across SW–PGND, minimizing dead-time losses and maximizing energy transfer efficiency. |

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 |
|---|---|---|---|
| MAX1605EEE+ | Lacks integrated IGBT driver; requires external gate driver and separate 50-V switch; no XFULL output; only 1.2 A max peak current. | Suitable for simpler, lower-power flash designs where external component count is acceptable and IGBT control is handled separately. | Select MAX1605EEE+ only if system already includes a discrete IGBT driver and thermal management is less constrained. |
| LT3494EDE#TRPBF | Higher VBAT range (up to 20 V); no integrated IGBT driver; uses external sense resistor for current limiting; no VFULL feedback - requires secondary-side optocoupler. | Preferred for industrial flash systems with wide-input rails and where isolation compliance mandates optocoupled feedback. | Choose LT3494EDE#TRPBF when input exceeds 12 V or regulatory standards require reinforced isolation not achievable with primary-side sensing. |
Compared with MAX1605EEE+ and LT3494EDE#TRPBF, the TPS65562RGTR uniquely integrates both the 50-V switch and IGBT driver in one QFN, delivers primary-side VFULL sensing for compactness, and provides programmable I_PEAK for battery-aware charging-making it optimal for space-constrained, high-integration consumer imaging designs.

FAQ
What is the maximum output voltage the TPS65562RGTR can charge a flash capacitor to?
The TPS65562RGTR charges flash capacitors to a nominal 29 V, with a factory-trimmed full-charge detection threshold (VFULL) of 28.6–29.4 V at the SW pin. This value is fixed and not user-adjustable; it reflects the internal comparator reference and is validated across temperature and process corners. The TPS65562RGTR does not support output voltages above 30 V due to its 50-V internal switch rating and VFULL architecture.
How does the TPS65562RGTR handle battery voltage variation during flash charging?
The TPS65562RGTR handles battery voltage variation through its programmable I_PEAK input: applying a lower voltage (e.g., 0 V) to I_PEAK sets peak switch current to 0.7–0.9 A for weak batteries, while 3 V sets it to 1.58–1.78 A for full batteries. This adaptive control maintains consistent charge time and energy delivery across the 1.6–12 V VBAT range, preventing over-stress on aging cells or under-performance with depleted ones.
Can the TPS65562RGTR drive an external IGBT without additional components?
Yes, the TPS65562RGTR can directly drive an external IGBT using its G_IGBT output, which provides push-pull drive from PGND to IGBT_VCC (2.7–5.5 V). No external gate resistor or level shifter is required for standard IGBTs with gate threshold ≤3 V and Qg ≤100 nC. However, layout must minimize trace inductance between G_IGBT and the IGBT gate, and IGBT_VCC must be decoupled with ≥1 μF ceramic capacitance near Pin 8.
What protection features are built into the TPS65562RGTR?
The TPS65562RGTR includes four hardware-enforced protections: (1) Overcurrent shutdown (OVDS) triggered when SW-to-PGND voltage exceeds 0.95–1.45 V; (2) Thermal shutdown at 150–170°C junction temperature; (3) MAX ON time limit (50–160 μs) preventing indefinite switch conduction; and (4) MAX OFF time limit (25–80 μs) forcing restart if zero-current detection fails. All protections cause immediate latch-off until CHG is cycled low-then-high.
Is the TPS65562RGTR RoHS-compliant and lead-free?
Yes, the TPS65562RGTR is RoHS-compliant and lead-free. Per TI's packaging addendum, it carries a "Pb-Free (RoHS)" eco-plan designation, meaning homogeneous materials contain ≤0.1% lead by weight and meet all six RoHS substance restrictions. The device is rated MSL-3 (Moisture Sensitivity Level 3) and qualified for lead-free reflow soldering per JEDEC J-STD-020.
