Product details
Overview
CAT3200TDI-GT-MP from onsemi is a fixed 5 V, low-noise regulated charge pump DC-DC converter delivering up to 100 mA output current from 2.7 V–4.5 V input, operating at constant 2 MHz switching frequency with 30 mVp-p output ripple and <1 µA shutdown current. It serves as a compact, capacitor-based boost supply for USB OTG, white LED drivers, and local 5 V rail generation in space-constrained portable devices.
For engineers reviewing the CAT3200TDI-GT-MP datasheet, pinout, applications, or equivalent options, key selection considerations include its TSOT-23-6 package footprint, fixed 5 V regulation without external feedback, thermal shutdown at 160°C, and compatibility with 1 µF ceramic flying/output capacitors.
Technical Context
The CAT3200TDI-GT-MP implements a non-overlapping 2-phase switched-capacitor voltage doubler architecture with internal 1.25 V reference and fixed resistor divider for regulation. Its control loop modulates charge pump current based on output error, enabling stable 5 V output across 0–100 mA load and 2.7–4.5 V input.
It integrates soft-start with slew-rate-limited power-up (≤0.5 ms), foldback current limiting (~225 mA short-circuit current), and thermal shutdown with 20°C hysteresis. The device isolates OUT from IN during shutdown while maintaining connection to internal feedback network, resulting in ≤30 µA reverse leakage into OUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% (ensures stable USB OTG or LED bias without external resistors) |
| Max Output Current | 100 mA continuous (supports 5 LEDs or single USB peripheral at full load) |
| Switching Frequency | 2.0 MHz typical (enables use of tiny 1 µF ceramic capacitors; reduces EMI filtering burden) |
| Input Voltage Range | 2.7 V to 4.5 V (matches Li-ion battery discharge curve and 3.3 V system rails) |
| Output Ripple | 30 mVp-p at 100 mA (meets noise-sensitive analog/RF circuit requirements) |
| Shutdown Current | <1 µA (preserves battery life in standby mode of handheld devices) |
| Thermal Shutdown | 160°C with 20°C hysteresis (prevents damage during sustained overload or high ambient) |
Pinout & Package
The CAT3200TDI-GT-MP is housed in a 6-lead TSOT-23 package (Case 419AF), 1 mm max height, RoHS-compliant NiPdAu lead finish, with 0.95 mm pitch and 2.90 mm × 1.60 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Power input | Accepts 2.7–4.5 V supply; requires 1 µF low-ESR ceramic bypass capacitor |
| 2: GND | Ground reference | Signal and power ground common node; must connect to PCB ground plane for thermal management |
| 3: SHDN | Active-low enable | CMOS input; logic LOW disables device and reduces IIN to <1 µA; no internal pull-down |
| 4: CNEG | Flying capacitor negative | Connects to negative terminal of 1 µF ceramic flying capacitor; avoids polarized caps |
| 5: CPOS | Flying capacitor positive | Connects to positive terminal of same flying capacitor; forms charge-transfer path |
| 6: OUT | Regulated output | Delivers fixed 5 V; requires 1 µF low-ESR ceramic output capacitor; isolated during shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Constant 2 MHz operation | Enables consistent EMI profile and predictable capacitor sizing-no frequency variation with load or temperature |
| Integrated thermal protection | Shuts down at 160°C junction temperature and auto-recovers at 140°C, preventing latch-up during sustained overload |
| Slew-rate controlled power-up | Limits inrush current to protect input source and downstream capacitance; achieves 90% VOUT in ≤0.5 ms |
| Low-value capacitor support | Operates reliably with 1 µF ceramic capacitors on IN, OUT, and flying nodes-reducing board area and cost vs. electrolytics |
| Foldback current limiting | Reduces output current under short-circuit to ~80 mA (typ), lowering power dissipation and thermal stress |
Applications
| USB OTG Power Supply | White LED Driver |
|---|---|
Use Scenario: Providing regulated 5 V power from a 3.3 V host system to enable USB On-The-Go functionality in smartphones or tablets. IC Role / Device Role / Timing Role: Fixed-output charge pump booster generating clean 5 V rail independent of host VBUS. Use Value: Eliminates need for inductor-based buck-boost ICs; meets USB 2.0 voltage tolerance (±4%) with 30 mVp-p ripple. | Use Scenario: Driving 3–5 white/blue LEDs from a single-cell Li-ion battery (3.0–4.2 V) in portable lighting or display backlighting. IC Role / Device Role / Timing Role: Efficient voltage booster supplying constant 5 V to LED string with current-limiting resistors. Use Value: Delivers 100 mA at >80% efficiency across battery discharge range; thermal shutdown prevents LED overdrive failure. |
| Local 5 V Rail Generation | Battery Backup System |
Use Scenario: Creating an isolated 5 V auxiliary supply from a lower-voltage system rail (e.g., 3.3 V FPGA core supply) for interface ICs or sensors. IC Role / Device Role / Timing Role: Compact, low-noise local regulator decoupled from main power domain. Use Value: TSOT-23-6 footprint fits tight layouts; 1.7 mA quiescent current minimizes impact on primary rail loading. | Use Scenario: Maintaining 5 V backup power to real-time clocks or SRAM during main supply interruption in industrial controllers or medical devices. IC Role / Device Role / Timing Role: Low-quiescent, shutdown-capable booster sustaining critical functions from coin cell or supercapacitor. Use Value: <1 µA shutdown current extends backup runtime; soft-start prevents voltage sag on weak backup sources. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX680ESA+ | Fixed 5 V output, ±1.5% accuracy, 100 mA max, 10 kHz switching, requires 10 µF flying cap | Lower frequency increases EMI filtering needs; larger capacitors increase board area | Prefer MAX680ESA+ only if ultra-low quiescent current (<10 µA) is prioritized over size and ripple |
| TPS60403DBVR | Fixed 5 V output, ±3% accuracy, 60 mA max, 1 MHz switching, supports 1 µF caps | Lower current rating limits to ≤3 white LEDs; less robust thermal protection (no hysteresis) | Choose TPS60403DBVR when 60 mA suffices and TI ecosystem integration is required |
Compared with CAT3200TDI-GT-MP, MAX680ESA+ trades higher ripple and larger capacitors for lower IQ, while TPS60403DBVR offers TI support but halves available output current and omits thermal hysteresis-making CAT3200TDI-GT-MP optimal for 100 mA, low-profile, thermally robust 5 V boosting.

FAQ
What is the output voltage tolerance of the CAT3200TDI-GT-MP under full load?
The CAT3200TDI-GT-MP delivers a fixed 5.0 V output with ±2% tolerance (4.8 V to 5.2 V) when load current is ≤100 mA and input voltage is ≥3.1 V. This specification is guaranteed per Table 4 in the official datasheet and ensures compatibility with USB 2.0 and standard 5 V logic interfaces without external trimming.
Does the CAT3200TDI-GT-MP require external feedback resistors to set the output voltage?
No, the CAT3200TDI-GT-MP does not require external feedback resistors. It is the fixed 5 V variant (CAT3200−5) with an internal resistor divider, unlike the adjustable CAT3200 which uses the FB pin. The CAT3200TDI-GT-MP has no FB pin and operates exclusively at 5 V output-simplifying design and reducing BOM count.
What is the maximum allowable input voltage for the CAT3200TDI-GT-MP?
The absolute maximum input voltage for the CAT3200TDI-GT-MP is +6.0 V, but the recommended operating range is strictly 2.7 V to 4.5 V. Exceeding 4.5 V may cause excessive power dissipation and premature thermal shutdown; operation above 6.0 V risks permanent damage per Absolute Maximum Ratings (Table 2).
Can the CAT3200TDI-GT-MP drive more than 100 mA continuously?
No, the CAT3200TDI-GT-MP is rated for 100 mA continuous output current under recommended conditions (TA = −40°C to +85°C, 2.7–4.5 V input). Attempting >100 mA triggers foldback current limiting (~80 mA short-circuit current) and may activate thermal shutdown at junction temperatures exceeding 160°C-making sustained overcurrent operation unsafe and unsupported.
Is the CAT3200TDI-GT-MP compatible with 0603-size 1 µF ceramic capacitors?
Yes, the CAT3200TDI-GT-MP is fully compatible with 0603-case 1 µF X5R or X7R ceramic capacitors for IN, OUT, and flying (CPOS/CNEG) positions. The datasheet explicitly recommends 1 µF ceramic caps and confirms stable operation with low-ESR types; avoid Z5U/Y5V due to voltage coefficient-induced capacitance loss.
