Product details
Overview
LTC3200ES6-5#TRPBF from Analog Devices (formerly Linear Technology) is a fixed-output, low-noise switched-capacitor voltage doubler IC delivering regulated 5V ±4% from 2.7V–4.5V input with up to 100mA output current at VIN ≥ 3.1V. It operates at constant 2MHz switching frequency, requires no inductors, and integrates soft-start and thermal shutdown-ideal for Li-ion battery-powered white LED backlighting and local 5V conversion in space-constrained portable devices.
For engineers reviewing the LTC3200ES6-5#TRPBF datasheet, LTC3200ES6-5#TRPBF pinout, LTC3200ES6-5#TRPBF application, or LTC3200ES6-5#TRPBF equivalent, key selection considerations include its ThinSOT-23-6 package, 1µA shutdown current, 30mVP-P output ripple at 100mA, fixed 5V regulation without external feedback, and compatibility with ceramic flying/output capacitors only.
Technical Context
The LTC3200ES6-5#TRPBF implements a 2-phase nonoverlapping charge-pump architecture that stacks a flying capacitor in series with VIN to generate VOUT ≈ 2×VIN, then regulates via internal resistor divider sensing. Its constant-frequency operation maintains stable ripple suppression across load range-including zero load-unlike variable-frequency charge pumps.
Regulation relies on linear control loop stability dominated by COUT capacitance (≥0.47µF required), with closed-loop output resistance of 0.5Ω enabling ≤50mV output deviation under 100mA load step. Input and output bypassing uses low-ESR ceramic capacitors exclusively; polarized capacitors are prohibited on C+ and C– terminals due to voltage reversal risk during startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5V ±4% - eliminates need for external feedback network; stable across 2.7V–4.5V input and 0–100mA load. |
| Input Voltage Range | 2.7V to 4.5V - matches single-cell Li-ion battery discharge profile; supports USB 3.3V–4.4V sources. |
| Max Output Current | 100mA at VIN ≥ 3.1V - sufficient for driving 5 white LEDs or powering PCMCIA 5V rails. |
| Switching Frequency | 2MHz (typ) - enables use of small 1µF ceramic flying/output capacitors; minimizes EMI filtering requirements. |
| Shutdown Current | <1µA - disconnects VOUT from VIN; critical for battery runtime extension in standby mode. |
| Output Ripple | 30mVP-P at VIN=3V, IOUT=100mA - low enough for noise-sensitive analog circuits without post-regulation LDO. |
| Efficiency | 80% at VIN=3V, IOUT=50mA - exceeds linear regulators in same voltage-doubling scenario; power loss modeled as (2×VIN − VOUT)×IOUT. |
Pinout & Package
Package: 6-pin ThinSOT-23 (S6), 1mm height, JEDEC SC-74A compatible - optimized for ultra-thin portable PCBs with minimal footprint (2.8mm × 2.9mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C+ | Flying capacitor positive terminal | Connects to + side of 1µF ceramic flying cap; voltage swings between VIN and ~2×VIN; must use non-polarized ceramic. |
| VIN | Input supply voltage | 2.7V–4.5V source input; requires 1µF low-ESR ceramic bypass to GND near pin to suppress high-frequency switching noise. |
| C– | Flying capacitor negative terminal | Connects to – side of flying cap; experiences reversed polarity during charge phase; prohibits tantalum/aluminum capacitors. |
| GND | Ground reference | Power ground for charge pump switches; must tie directly to solid ground plane to minimize thermal resistance (θJA = 175°C/W). |
| SHDN | Active-low shutdown control | CMOS input with 0.4V/1.3V logic thresholds; floating state undefined; drives low to reduce ICC to <1µA and isolate VOUT from VIN. |
| VOUT | Regulated 5V output | Delivers up to 100mA; requires 1µF ceramic bypass; output impedance 0.5Ω ensures ≤50mV droop under full load step. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor voltage doubling | Eliminates magnetic components, EMI filters, and layout sensitivity-reduces BOM count to just three 1µF ceramics. |
| Constant 2MHz frequency | Enables predictable EMI filtering and consistent ripple behavior across all loads, including zero-current standby. |
| Integrated soft-start | Prevents >100mA inrush into 10µF output caps; start-up time ~1ms; avoids input supply sag in battery systems. |
| Thermal shutdown | Disables charge pump at ~160°C junction temperature; auto-restarts at ~155°C-enables indefinite short-circuit survival. |
| Short-circuit protection | Limits output current to ~225mA during VOUT-to-GND fault-prevents device damage without external current-sense circuitry. |
Applications
| White LED Backlighting | Li-Ion Battery Backup Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar charge-pump voltage doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1754ES6-5#TRPBF | Same S6 package, but 13µA shutdown current vs. 1µA; 50mA max output vs. 100mA; 2MHz frequency. | Lower output current limits use in multi-LED or high-load scenarios; higher shutdown current reduces battery life in always-on backup. | Select LTC3200ES6-5#TRPBF when >50mA load or <5µA shutdown is required. |
| LTC1928ES6-5#TRPBF | Integrates low-noise LDO post-regulator; 60µVRMS noise vs. 30mVP-P; 50mA output; same S6 package. | Superior noise performance for RF/analog circuits, but reduced output current and added quiescent overhead. | Select LTC3200ES6-5#TRPBF when ripple-limited digital loads dominate and cost/size favor simpler architecture. |
Compared with LTC1754ES6-5#TRPBF and LTC1928ES6-5#TRPBF, the LTC3200ES6-5#TRPBF provides highest output current (100mA) and lowest shutdown current (1µA) in the ThinSOT-23-6 form factor-making it optimal for battery-critical, moderate-power applications where LDO-level noise is unnecessary.

FAQ
What is the maximum continuous output current of the LTC3200ES6-5#TRPBF?
The LTC3200ES6-5#TRPBF delivers up to 100mA continuously when input voltage is ≥3.1V. At lower inputs (2.7V–3.0V), maximum output current is limited to 40mA to maintain regulation within 5V ±4%. This is defined by internal current-limiting and thermal design-not adjustable externally.
Can the LTC3200ES6-5#TRPBF operate from a 5V input source?
The LTC3200ES6-5#TRPBF has an absolute maximum VIN rating of 6V, so 5V operation is electrically permissible. However, at VIN > 4.5V, output voltage may rise above 5.2V under light loads due to charge-pump coupling; a 5kΩ bleed resistor from VOUT to GND restores regulation. For reliable 5V output, keep VIN ≤ 4.5V.
Why does the LTC3200ES6-5#TRPBF require ceramic capacitors only?
The LTC3200ES6-5#TRPBF's charge-pump topology reverses polarity across the flying capacitor (C+ and C–) during startup and operation. Tantalum or aluminum electrolytics cannot withstand reverse voltage and will fail catastrophically. Ceramic capacitors provide necessary non-polarity, low ESR (<0.1Ω), and stable capacitance over temperature/voltage.
How does the LTC3200ES6-5#TRPBF achieve low output ripple without an inductor?
The LTC3200ES6-5#TRPBF uses constant-frequency 2MHz switching and a tightly controlled linear regulation loop referenced to its internal 5V divider. Combined with low-ESR ceramic output capacitors (≥1µF), this achieves 30mVP-P ripple at full load-comparable to many inductor-based converters-while eliminating magnetic components and their associated EMI and size penalties.
Is the LTC3200ES6-5#TRPBF pin-compatible with other ThinSOT-6 charge pumps?
No. While the LTC3200ES6-5#TRPBF shares the S6 package outline with LTC1754ES6-5#TRPBF and LTC1928ES6-5#TRPBF, pin functions differ: LTC3200ES6-5#TRPBF assigns Pin 4 to GND and Pin 2 to VIN, whereas LTC1754 uses Pin 4 for SHDN and Pin 2 for GND. PCB layout must be verified per each device's datasheet pinout.
