Product details
Overview
LT8362EMSE#PBF from Analog Devices is a current-mode DC/DC converter IC with a 60V, 2A internal power switch, operating from 2.8V to 60V input. It supports boost, SEPIC, and inverting topologies via a single FBX feedback pin, delivers 9µA quiescent current in Burst Mode, and maintains <15mV output ripple-enabling compact, high-efficiency power supplies for automotive infotainment and industrial sensors.
For engineers reviewing the LT8362EMSE#PBF datasheet, LT8362EMSE#PBF pinout, LT8362EMSE#PBF application, or LT8362EMSE#PBF equivalent, key selection factors include its 300kHz–2MHz programmable switching frequency, SYNC/MODE pin for EMI-optimized spread-spectrum operation, BIAS pin for efficiency enhancement, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The LT8362EMSE#PBF implements fixed-frequency current-mode control with external RT-resistor-programmable oscillator (300kHz–2MHz) and dual-path error amplification-selecting between +1.60V or −0.80V internal references based on FBX polarity to support positive or negative output configurations. Its Burst Mode architecture enables ultralow 9µA IQ while maintaining tight regulation and sub-15mV ripple at light loads.
Switch control integrates minimum on-time (70ns typ.) and off-time (50ns typ.) constraints, frequency foldback during overload, and overtemperature shutdown (>170°C). The SYNC/MODE pin provides five distinct operational modes-including synchronized pulse-skipping, Burst Mode, and spread-spectrum modulation-without requiring external logic or configuration registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8V to 60V - supports wide-range battery and industrial bus inputs without pre-regulation |
| Switch Rating | 60V, 2A - enables 48V boost outputs up to 700mA at 24V input in typical applications |
| Quiescent Current | 9µA in Burst Mode - sustains >85% efficiency at 100µA load, critical for always-on systems |
| Feedback Reference | +1.60V or −0.80V - single FBX pin supports both positive and negative output topologies |
| Switching Frequency | 300kHz to 2MHz - programmable via RT resistor; higher frequencies reduce inductor size |
| Package | 16-lead MSOP with 4 pins removed - thermally enhanced, exposed PGND pad for 45°C/W θJA |
| Temperature Range | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
Pinout & Package
The LT8362EMSE#PBF is housed in a thermally enhanced 16-lead plastic MSOP package with four pins removed (MSE16 variation), featuring an exposed PGND/GND pad (Pin 17) that must be soldered to PCB ground for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN/UVLO | Enable / Undervoltage Lockout Input | 1.6V rising threshold with 80mV hysteresis; ties directly to VIN for always-on operation or resistive divider for programmable UVLO |
| VIN | Main Input Supply | Accepts 2.8V–60V; requires local ceramic bypass near pin and exposed pad |
| INTVCC | Internal 3.2V Regulator Output | Bypass with 1µF ceramic; no external loading permitted; powered by BIAS if 4.4V ≤ BIAS ≤ VIN |
| BIAS | Secondary Input for INTVCC | Reduces VIN current draw when supplying INTVCC; improves full-load efficiency in SEPIC/boost designs |
| VC | Error Amplifier Output | Connects to external compensation network (R-C across VC–FBX) for loop stability optimization |
| FBX | Feedback Input | Single pin accepts either +1.60V (boost/SEPIC) or −0.80V (inverting) reference; sets output voltage via resistor divider |
| RT | Frequency Programming | Resistor to GND sets switching frequency from 300kHz to 2MHz; formula: RT(kΩ) = 51.2/fOSC(MHz) − 5.6 |
| SS | Soft-Start Control | Capacitor to GND controls inductor current ramp rate; 2µA charge current; internal 220Ω discharge during fault |
| SYNC/MODE | Mode Selection & Clock Sync | Five modes: GND = Burst; float = pulse-skip; INTVCC = pulse-skip+SSFM; 100k-to-GND = Burst+SSFM; external clock = sync+pulse-skip |
| SW | Power Switch Output | 60V, 2A NMOS drain; minimize trace area to reduce EMI; connects to inductor/diode node |
| PGND/GND | Power & Signal Ground | Exposed pad (Pin 17) is primary thermal path and low-impedance return for SW, EN/UVLO, and FBX circuits |
Key Features
| Feature | Design Value |
|---|---|
| Single-FB Topology Flexibility | One feedback pin supports boost, SEPIC, and inverting configurations-reducing BOM count and layout complexity |
| Burst Mode Efficiency | 9µA IQ with <15mV output ripple preserves battery life in standby while meeting low-noise analog supply requirements |
| Spread-Spectrum Modulation | 20% frequency deviation at fOSC/256 reduces peak EMI by >10dB without adding filtering components |
| BIAS-Pin Efficiency Boost | Redirects INTVCC current from VIN to BIAS (4.4V–VIN), cutting input supply loss by up to 40% in high-VIN SEPIC designs |
| Programmable UVLO | Resistive divider on EN/UVLO sets precise turn-on/off thresholds (e.g., 8V–10V hysteresis) for system-level brownout protection |

FAQ
What is the maximum output voltage achievable with LT8362EMSE#PBF in boost configuration?
The LT8362EMSE#PBF supports output voltages up to 60V in boost mode, limited by its 60V-rated internal switch and absolute maximum SW pin rating. Practical output is constrained by external component ratings (diode, capacitor, inductor) and layout parasitics. At VIN = 12V, typical 48V/200mA operation is demonstrated in the datasheet with <15mV ripple in Burst Mode.
Does LT8362EMSE#PBF require external MOSFETs for operation?
No, the LT8362EMSE#PBF integrates a 60V, 2A NMOS power switch and does not require external MOSFETs. It operates as a complete controller+switch solution in boost, SEPIC, and inverting topologies. External components needed are diode, inductor, input/output capacitors, feedback resistors, and optional RT/SS/compensation components.
How does the BIAS pin improve efficiency in LT8362EMSE#PBF designs?
The BIAS pin on the LT8362EMSE#PBF supplies the internal 3.2V INTVCC regulator when 4.4V ≤ BIAS ≤ VIN, diverting up to 1.6mA of bias current away from VIN. In SEPIC applications where VOUT ≈ VIN, connecting BIAS to VOUT reduces total input current and improves full-load efficiency by up to 40% compared to VIN-only operation.
Can LT8362EMSE#PBF generate negative output voltages?
Yes, the LT8362EMSE#PBF supports inverting topology using the same FBX pin, which references to −0.80V internally. A resistor divider from VOUT (negative rail) to GND sets output voltage via R1 = R2 × (|VOUT|/0.80V − 1). This eliminates need for separate inverting controllers and simplifies bipolar supply generation.
What is the purpose of the SYNC/MODE pin on LT8362EMSE#PBF?
The SYNC/MODE pin on LT8362EMSE#PBF selects among five operational modes: Burst Mode (GND), pulse-skipping (floating), spread-spectrum + pulse-skip (INTVCC), Burst + SSFM (100k-to-GND), or external clock synchronization (square wave 0.4–6V). This enables EMI reduction, efficiency optimization, and system-level timing alignment without external logic.
