Product details
Overview
LTC3410BESC6-1.2#TRMPBF from Analog Devices (formerly Linear Technology) is a monolithic synchronous step-down DC/DC regulator in SC70-6 package, delivering up to 300mA output at 1.2V with 2.5V–5.5V input, 2.25MHz fixed switching frequency, and ±2% output voltage accuracy. It enables compact, high-efficiency power conversion in single-cell Li-ion portable systems requiring low dropout and ceramic-capacitor compatibility.
For engineers reviewing the LTC3410BESC6-1.2#TRMPBF datasheet, LTC3410BESC6-1.2#TRMPBF pinout, LTC3410BESC6-1.2#TRMPBF application, or LTC3410BESC6-1.2#TRMPBF equivalent, key selection criteria include its 1.2V fixed output, 2.25MHz operation enabling sub-2mm inductors, 100% duty cycle capability for ultra-low dropout, and internal synchronous FETs eliminating external Schottky diodes.
Technical Context
The LTC3410BESC6-1.2#TRMPBF employs constant-frequency current-mode control with integrated P-channel main and N-channel synchronous switches. Its 0.8V internal reference and fixed 1.2V output are achieved via internal resistor divider, eliminating external feedback components. Pulse-skipping mode maintains regulation at light loads while minimizing output ripple.
Thermal design relies on SC70-6's 250°C/W junction-to-ambient thermal resistance; overtemperature protection disables both switches above ~150°C. Input undervoltage lockout activates below 1.94V (falling) and releases above 2.3V (rising), ensuring stable startup across battery discharge profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% (1.176V–1.224V) at 100mA load; supports Li-ion battery discharge down to 2.7V input |
| Input Voltage Range | 2.5V to 5.5V DC; compatible with single-cell Li-ion (2.7V–4.2V) and regulated 3.3V/5V rails |
| Switching Frequency | 2.25MHz (typical); enables use of 2.2µH–4.7µH shielded inductors ≤2mm height and 2.2µF ceramic capacitors |
| Max Output Current | 300mA continuous at VIN = 3V; peak switch current limited to 380mA minimum (630mA absolute max) |
| Efficiency | Up to 96% at mid-load; optimized by synchronous rectification and low RDS(ON) FETs (0.75Ω P-ch / 0.55Ω N-ch) |
| Quiescent Current | 200µA operating / <1µA shutdown; extends battery life in standby modes of portable devices |
| Duty Cycle | 100% capability enables dropout operation when VIN approaches VOUT; critical for end-of-battery-life runtime |
Pinout & Package
Package: 6-lead plastic SC70 (SC6), 1.80–2.20mm × 1.15–1.35mm × 0.80–1.00mm height, moisture sensitivity level 1, lead-free (Pb-free) termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable control input | Logic-high (>1.5V) enables regulation; logic-low (<0.3V) forces shutdown with <1µA supply current; must not float |
| GND (Pins 2, 5) | Power and signal ground | Dual ground pins reduce PCB trace inductance and improve thermal dissipation; connect directly to power plane |
| SW (Pin 3) | Switch node | Connects to inductor; carries high di/dt square-wave current; requires short, wide copper pour to minimize EMI |
| VIN (Pin 4) | Main input supply | Accepts 2.5V–5.5V; requires local 2.2µF ceramic decoupling capacitor placed adjacent to pin |
| VOUT (Pin 6) | Fixed-output feedback | Internally connected to 1.2V output divider; no external resistors needed; enables remote sensing via PCB trace |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Eliminates external Schottky diode, increasing efficiency by ~5–10% and reducing board area vs. asynchronous buck |
| Ceramic capacitor stability | Control loop independent of output capacitor ESR, enabling use of low-ESR X5R/X7R ceramics for <10mVpp ripple |
| 100% duty cycle operation | Maintains regulation down to VIN = VOUT + ILOAD × RDS(ON); extends usable battery voltage range by ~150mV |
| Pulse-skipping light-load mode | Reduces switching losses at ILOAD < 10mA, maintaining >80% efficiency without audible noise or burst-mode artifacts |
| Overtemperature protection | Thermal shutdown disables both FETs above ~150°C junction temperature; auto-recovery after cooldown |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYR | 1.2V fixed, 2.25MHz, 300mA, but uses voltage-mode control and lacks 100% duty cycle | Lower light-load efficiency due to lack of pulse-skipping; higher dropout voltage limits battery runtime | Choose if requiring TI ecosystem support or lower cost at expense of end-of-discharge performance |
| MAX17222ATA+T | 1.2V fixed, 2.5MHz, 400mA, with integrated soft-start and higher quiescent current (500µA) | Better transient response for pulsed loads but reduced battery life in always-on sensor nodes | Prefer when fast load-step recovery is critical and 300mA peak suffices; verify thermal margin in SC70 |
Compared with TPS62231DRYR and MAX17222ATA+T, the LTC3410BESC6-1.2#TRMPBF delivers superior battery-endurance via 100% duty cycle and <1µA shutdown, while maintaining identical 2.25MHz/300mA/1.2V specs and SC70-6 footprint-making it optimal for ultra-portable Li-ion systems where every millivolt counts.

FAQ
What is the maximum continuous output current of the LTC3410BESC6-1.2#TRMPBF?
The LTC3410BESC6-1.2#TRMPBF delivers up to 300mA continuous output current when VIN = 3V, as specified in the datasheet. Peak inductor current capability is 380mA minimum (630mA absolute max), and thermal limits in the SC70-6 package require careful layout and ambient temperature management above 200mA in enclosed environments.
Does the LTC3410BESC6-1.2#TRMPBF require external feedback resistors?
No, the LTC3410BESC6-1.2#TRMPBF is a fixed-output variant with internal resistor divider connecting Pin 6 (VOUT) to the 0.8V reference. Unlike adjustable versions (e.g., LTC3410BE), it needs no external R1/R2 network-simplifying layout and improving accuracy by eliminating resistor tolerance errors.
Can the LTC3410BESC6-1.2#TRMPBF operate with input voltage below 2.5V?
No-the absolute minimum input voltage is 2.5V per datasheet specifications. Below this, undervoltage lockout engages (UVLO threshold is 1.94V falling / 2.3V rising), preventing regulation. Attempting operation below 2.5V risks unstable output or failure to start, especially near end-of-battery-life at ~2.7V nominal.
What is the purpose of the RUN pin on the LTC3410BESC6-1.2#TRMPBF?
The RUN pin (Pin 1) provides enable/disable control: driving it above 1.5V activates regulation, while pulling it below 0.3V places the LTC3410BESC6-1.2#TRMPBF in shutdown mode drawing <1µA. It must never be left floating, as indeterminate logic levels may cause erratic startup or increased quiescent current.
Which ceramic capacitor dielectrics are recommended for use with the LTC3410BESC6-1.2#TRMPBF?
X5R and X7R dielectric ceramic capacitors are explicitly recommended for both input (CIN) and output (COUT) in the LTC3410BESC6-1.2#TRMPBF datasheet. These offer stable capacitance vs. temperature and voltage, low ESR, and high ripple-current ratings-critical for achieving <10mVpp output ripple and avoiding input ringing in battery-powered systems.
