Product details
Overview
LTC1754ES6-5#TRPBF from Analog Devices (formerly Linear Technology) is a micropower regulated 5V charge pump DC/DC converter in a 6-pin SOT-23 package. It delivers up to 50mA output current with ±4% regulation, draws only 13µA quiescent current, features 600kHz internal oscillator, and includes shutdown disconnect and thermal protection. It is used in GSM SIM interface supplies and Li-ion battery-powered white LED drivers.
For engineers reviewing the LTC1754ES6-5#TRPBF datasheet, LTC1754ES6-5#TRPBF pinout, LTC1754ES6-5#TRPBF application, or LTC1754ES6-5#TRPBF equivalent, key selection criteria include input voltage range (2.7V–5.5V), regulated 5V ±4% output, ultralow 13µA operating current, <1µA shutdown current, and SOT-23 footprint compatibility for space-constrained portable designs.
Technical Context
The LTC1754ES6-5#TRPBF operates as a Burst Mode™ switched-capacitor voltage doubler with hysteresis-based regulation. It senses VOUT via an internal resistor divider and enables the charge pump when the divided voltage falls below the lower comparator threshold; regulation is maintained by cycling between charging (CFLY to VIN) and stacking (CFLY + VIN to VOUT) phases.
Its control architecture integrates thermal shutdown (trip at ~150°C, restart at ~140°C), short-circuit protection (indefinite survival), CMOS SHDN input with 0.8V threshold, and automatic load-disconnect during shutdown. The device uses no inductors and relies on a single 1µF flying capacitor and two 10µF bypass capacitors for full functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±4% - tightly regulated for powering 5V logic, USB peripherals, or white LEDs without external feedback. |
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion (3.0–4.2V), 3.3V rails, and 5V USB inputs with margin. |
| Max Output Current | 50mA at VIN ≥ 3.0V - sufficient for SIM cards, smart card readers, and low-power microcontrollers. |
| Quiescent Current | 13µA typical - enables multi-year battery life in always-on backup or sensor nodes. |
| Shutdown Current | <1µA - ensures negligible drain during system sleep, critical for coin-cell or energy-harvesting systems. |
| Switching Frequency | 600kHz - enables use of small 1µF ceramic flying capacitor and minimizes EMI in RF-sensitive layouts. |
| Package | SOT-23-6 - 0.052 inch² total PCB area; compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: 6-Lead Plastic SOT-23 (JEDEC MO-178AA, EIAJ SC-74A), 2.80–3.00 mm × 1.90 mm × 1.15 mm, thermal resistance θJA = 230°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Regulated output node | Delivers stable 5V ±4%; requires ≥10µF low-ESR capacitor at pin for ripple suppression and stability. |
| GND (Pin 2) | Power and signal reference | Must connect to solid ground plane; serves as return path for all internal switching currents and sensing. |
| SHDN (Pin 3) | Active-low enable control | CMOS input with ~0.8V threshold; must be driven-never left floating-to ensure defined startup/shutdown behavior. |
| C– (Pin 4) | Flying capacitor negative terminal | Connects to negative side of 1µF ceramic flying capacitor; forms charge-transfer path during pumping cycles. |
| VIN (Pin 5) | Input supply input | Accepts 2.7–5.5V; requires ≥10µF low-ESR bypass capacitor close to pin to handle 50–100mA transient currents. |
| C+ (Pin 6) | Flying capacitor positive terminal | Connects to positive side of 1µF flying capacitor; switches between VIN and VOUT nodes in two-phase operation. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor topology | Eliminates magnetic components and EMI concerns-ideal for RF-dense handhelds and SIM modules. |
| Load disconnect in shutdown | Isolates VOUT from VIN during SHDN, preventing backfeed and enabling true zero-load standby. |
| Thermal shutdown with hysteresis | Auto-recovers from overtemperature events (e.g., sustained short circuit) without latch-up or manual reset. |
| Ultrasmall solution size | 0.052 inch² total layout area using only three external capacitors-fits inside tight PCMCIA or smartcard footprints. |
| Burst Mode™ regulation | Maintains high efficiency (>82%) even at light loads (e.g., 1mA) by pulsing the charge pump only when needed. |

FAQ
What is the minimum input voltage required for the LTC1754ES6-5#TRPBF to deliver full 50mA output?
The LTC1754ES6-5#TRPBF requires VIN ≥ 3.0V to sustain 50mA output current while maintaining 5V ±4% regulation. Below 3.0V, output current capability drops-e.g., at VIN = 2.7V, max IOUT is 25mA. This is specified in the Electrical Characteristics table under "VOUT Output Voltage" conditions for the LTC1754-5 variant.
Does the LTC1754ES6-5#TRPBF require external feedback resistors to set the output voltage?
No, the LTC1754ES6-5#TRPBF does not require external feedback resistors. Its 5V output is internally regulated via a precision resistor divider and comparator (COMP1), as shown in the Simplified Block Diagram. The output voltage is fixed at 5.0V ±4% and cannot be adjusted externally.
Can the LTC1754ES6-5#TRPBF drive multiple white LEDs in series?
No-the LTC1754ES6-5#TRPBF is a regulated voltage source, not a constant-current driver. To drive white LEDs, it must be paired with an external current-limiting resistor or a separate LED driver IC. Its 5V output can power one or two parallel white LEDs (VF ≈ 3.0–3.6V), but not three in series (requiring >9V).
What is the recommended flying capacitor value and type for the LTC1754ES6-5#TRPBF?
The recommended flying capacitor for the LTC1754ES6-5#TRPBF is 1µF ceramic (X7R or C0G), placed as close as possible between C+ (Pin 6) and C– (Pin 4). A minimum of 0.6µF is required for full 50mA output; larger values (up to 2.2µF) improve ripple but increase board area and cost.
Is the LTC1754ES6-5#TRPBF pin-compatible with the LTC1754ES6-3.3#TRPBF?
Yes-the LTC1754ES6-5#TRPBF and LTC1754ES6-3.3#TRPBF share identical SOT-23-6 pinout, package dimensions, and control logic (SHDN, GND, VIN, etc.). They differ only in internal feedback ratio and output voltage specification; swapping them requires verifying downstream 3.3V vs 5V compatibility.
