Product details
Overview
LTC3200ES6-5#TRMPBF 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. 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 compact 3V-to-5V local conversion.
For engineers reviewing the LTC3200ES6-5#TRMPBF datasheet, LTC3200ES6-5#TRMPBF pinout, LTC3200ES6-5#TRMPBF application, or LTC3200ES6-5#TRMPBF equivalent, key selection criteria include its ThinSOT-23-6 package, 1µA shutdown current, 30mVP-P output ripple at 100mA, and compatibility with ceramic flying/output capacitors down to 1µF.
Technical Context
The LTC3200ES6-5#TRMPBF 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 feedback. Its constant-frequency operation maintains stable ripple suppression across load range-including zero load-unlike variable-frequency charge pumps.
Regulation is achieved by modulating charge-pump current strength based on error between internal 1.268V reference and sensed VOUT. The device includes CMOS-level SHDN control (VIH = 1.3V, VIL = 0.4V), built-in soft-start (~1ms ramp), and thermal shutdown activation at ~160°C with automatic recovery at ~155°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5V ±4% - ensures stable 5V rail for USB peripherals or logic without external feedback components. |
| Input Voltage Range | 2.7V to 4.5V - matches single-cell Li-ion battery discharge profile (3.0–4.2V typical) with 0.3V headroom margin. |
| Max Output Current | 100mA at VIN ≥ 3.1V - supports driving 5 white LEDs (20mA each) or powering small microcontrollers and sensors. |
| Switching Frequency | 2MHz (typ) - enables use of tiny 1µF ceramic capacitors instead of bulky electrolytics or inductors. |
| Shutdown Current | <1µA - preserves battery life during system sleep modes without requiring external load switches. |
| Output Ripple | 30mVP-P at VIN = 3V, IOUT = 100mA - low enough for noise-sensitive analog circuits and LED drivers without added LDO filtering. |
| Efficiency | 80% at VIN = 3V, IOUT = 50mA - exceeds linear regulators in same input-output delta, minimizing thermal stress in sealed enclosures. |
Pinout & Package
Package: 6-pin ThinSOT-23 (S6), 1mm height, JEDEC SC-74A compliant, with exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C+ | Flying capacitor positive terminal | Connects to high-side plate of 1µF ceramic flying cap; must be low-ESR and non-polarized (e.g., X5R/X7R). |
| VIN | Input supply voltage | Accepts 2.7–4.5V; requires 1µF ceramic bypass close to pin to suppress high-frequency switching noise. |
| C− | Flying capacitor negative terminal | Connects to low-side plate of flying cap; forms charge-transfer path with C+ during clock phases. |
| GND | Power ground | Primary return path for charge pump and output current; must connect directly to solid ground plane for thermal and EMI control. |
| SHDN | Active-low shutdown control | CMOS input; drives low (≤0.4V) to disable IC and disconnect VOUT from VIN, reducing IQ to <1µA. |
| VOUT | Regulated 5V output | Delivers up to 100mA; requires 1µF ceramic output cap adjacent to pin to stabilize control loop and limit ripple. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic components and EMI from inductive switching, enabling ultra-thin PCB designs for portable electronics. |
| Constant 2MHz frequency | Ensures predictable EMI spectrum and consistent capacitor sizing-no frequency jitter or load-dependent variation. |
| Integrated soft-start | Prevents >100mA inrush into 10µF output caps, avoiding brown-out on shared battery rails during power-up. |
| Thermal + short-circuit protection | Survives indefinite VOUT-to-GND shorts and auto-recovers from junction overheating (>160°C), enhancing field reliability. |
| Low-noise regulation | 30mVP-P ripple at full load meets requirements for analog sensor supplies and LED current-source references. |
Applications

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#TRMPBF | Higher shutdown current (13µA vs. <1µA); lower max output current (50mA vs. 100mA); same S6 package. | Suitable for lower-power smart card or sensor bias where ultra-low IQ is less critical. | Choose LTC1754ES6-5#TRMPBF only if design tolerates 13× higher shutdown IQ and reduced load capability. |
| LTC1928ES6-5#TRMPBF | Integrates low-noise LDO post-regulator (60µVRMS noise); lower efficiency (≈70%); same 5V output and S6 package. | Better for noise-sensitive analog front-ends (e.g., ADC references) where ripple must be <100µVRMS. | Select LTC1928ES6-5#TRMPBF when output noise-not just ripple-is the dominant constraint, accepting efficiency penalty. |
Compared with LTC1754ES6-5#TRMPBF and LTC1928ES6-5#TRMPBF, the LTC3200ES6-5#TRMPBF delivers the highest output current (100mA) and lowest shutdown current (<1µA) in the ThinSOT-6 form factor, making it optimal for battery-constrained, medium-load applications where simplicity and efficiency are prioritized over ultra-low noise or extended temperature range.

FAQ
What is the maximum continuous output current of the LTC3200ES6-5#TRMPBF?
The LTC3200ES6-5#TRMPBF delivers up to 100mA continuously when input voltage is ≥3.1V and ambient temperature remains within –40°C to 85°C. At lower VIN (2.7V–3.0V), max output current reduces to 40mA to maintain regulation and thermal safety. This is confirmed in the Electrical Characteristics table under "VOUT" conditions and validated by Figure G02 (Output Voltage vs Load Current).
Does the LTC3200ES6-5#TRMPBF require external feedback resistors?
No, the LTC3200ES6-5#TRMPBF does not require external feedback resistors because it features an internal resistor divider that fixes the output voltage at 5V ±4%. Unlike the adjustable LTC3200 variant (which uses the FB pin), the LTC3200ES6-5#TRMPBF omits the FB pin entirely-confirmed by its 6-pin ThinSOT pinout (C+, VIN, C−, GND, SHDN, VOUT) and the "Fixed 5V ±4% Output" feature listing.
Can the LTC3200ES6-5#TRMPBF operate with input voltages above 4.5V?
The absolute maximum VIN rating for the LTC3200ES6-5#TRMPBF is 6V, but recommended operating range is strictly 2.7V to 4.5V per datasheet specifications. Operation above 4.5V may cause output overvoltage at light loads due to charge coupling, and efficiency/thermal performance degrades significantly-Figure G07 shows short-circuit current rising sharply above 4.5V, indicating stress on internal switches.
What ceramic capacitor dielectric is recommended for the flying capacitor in the LTC3200ES6-5#TRMPBF?
Murata GRM39X5R105K6.3AJ or Taiyo Yuden JMK107BJ105MA-both X5R-class 1µF/6.3V ceramics-are explicitly recommended in the datasheet (page 1). X5R offers stable capacitance across –40°C to 85°C and low voltage coefficient, unlike Z5U/Y5V types which can lose >60% capacitance at rated voltage-critical for maintaining 100mA output capability.
Is thermal shutdown reversible on the LTC3200ES6-5#TRMPBF?
Yes, thermal shutdown on the LTC3200ES6-5#TRMPBF is fully reversible: the device disables the charge pump when junction temperature exceeds ~160°C and automatically resumes normal operation once temperature falls to ~155°C. This hysteresis prevents oscillation, and the datasheet confirms indefinite cycling "without latch-up or damage" (page 6, Short-Circuit/Thermal Protection section).
