Product details
Overview
LT8362HMSE#TRPBF 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 48V output at up to 700mA (VIN = 24V), and achieves ultralow 9µA quiescent current in Burst Mode for battery-powered telecom and portable medical equipment.
For engineers reviewing the LT8362HMSE#TRPBF datasheet, LT8362HMSE#TRPBF pinout, LT8362HMSE#TRPBF application, or LT8362HMSE#TRPBF equivalent, this page provides verified topology flexibility, thermal-grade packaging (–40°C to 150°C), programmable 300kHz–2MHz switching, BIAS-pin efficiency optimization, and AEC-Q100-qualified operation for automotive subsystems.
Technical Context
The LT8362HMSE#TRPBF implements fixed-frequency current-mode control with external RT-resistor programmability and dual-path error amplification-A1 active for positive outputs (1.60V reference), A2 for negative outputs (–0.80V reference). Its SYNC/MODE pin enables five distinct operational modes: Burst Mode (<0.14V), pulse-skipping (floating), SSFM-enabled pulse-skip (>1.7V), external clock sync, or Burst+SSFM (100kΩ-to-GND).
It integrates frequency foldback, programmable soft-start (2µA charge current), UVLO with 80mV hysteresis (1.576V rising / 1.555V falling), and thermal shutdown at >170°C. The BIAS pin supplies INTVCC when 4.4V ≤ BIAS ≤ VIN, reducing VIN current draw and improving full-load efficiency in SEPIC or high-VIN boost configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8V to 60V - supports wide-range industrial rails, automotive battery transients, and legacy telecom supplies. |
| Switch Rating | 60V, 2A - enables 48V boost output with margin for diode drop and transient spikes. |
| Quiescent Current (Burst) | 9µA - sustains >1000-hour battery life in always-on portable diagnostics with <15mV ripple. |
| Switching Frequency | 300kHz to 2MHz - adjustable via RT resistor; 2MHz operation allows <2.2µH inductors and compact layouts. |
| Feedback Reference | +1.60V or –0.80V - single FBX pin supports both positive and negative output topologies without external op-amps. |
| Operating Junction Temp | –40°C to 150°C - H-grade qualification ensures reliability in under-hood automotive modules and industrial motor drives. |
| Package Thermal Resistance | θJA = 45°C/W (MSOP) - exposed pad (Pin 17) must be soldered to PCB ground plane for thermal integrity. |
Pinout & Package
LT8362HMSE#TRPBF uses a thermally enhanced 16-lead MSOP package with four pins removed (MSE16 variation), featuring an exposed PGND/GND pad (Pin 17) that must be soldered to PCB copper for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN/UVLO | Enable / Input Undervoltage Lockout | 1.6V threshold with 80mV hysteresis; <0.2V reduces VIN current to <1µA for deep sleep. |
| VIN | Main Input Supply | Bypass locally with low-ESR capacitor; powers INTVCC unless BIAS is active and within 4.4V–VIN range. |
| INTVCC | Internal 3.2V Regulator Output | Must be bypassed with 1µF ceramic; not externally loaded; enables gate drive and internal logic. |
| BIAS | Secondary Input for INTVCC | Supplies INTVCC when 4.4V ≤ BIAS ≤ VIN, offloading VIN and improving efficiency by >5% at full load. |
| VC | Error Amplifier Output | Connect external compensation network (RC, CC) here to stabilize loop across wide VIN/VOUT ranges. |
| FBX | Feedback Input (±1.6V/–0.8V) | Single pin configures boost (+1.6V ref) or inverting (–0.8V ref); regulates output voltage via R1/R2 divider. |
| RT | Frequency Programming | Resistor to GND sets fSW from 300kHz (165kΩ) to 2MHz (20kΩ); enables EMI-optimized layout choices. |
| SS | Soft-Start Control | 2µA constant-current ramp; capacitor value controls inductor current slew rate during startup. |
| SYNC/MODE | Mode Selection & Clock Sync | Five modes: Burst (<0.14V), Pulse-Skip (float), SSFM+Pulse-Skip (>1.7V), Sync (external clock), Burst+SSFM (100kΩ-to-GND). |
| SW1/SW2 | Power Switch Outputs | 60V, 2A NMOS drain/source terminals; minimize trace area to reduce EMI radiation. |
| PGND/GND | Power & Signal Ground | Exposed pad (Pin 17) is primary thermal path and low-impedance return for SW and PGND currents. |
Key Features
| Feature | Design Value |
|---|---|
| Topology Flexibility | Single FBX pin supports boost, SEPIC, and inverting configurations without external reconfiguration circuitry. |
| Ultralow IQ Operation | 9µA Burst Mode quiescent current maintains high light-load efficiency while holding output ripple <15mV. |
| EMI Reduction | Spread Spectrum Frequency Modulation (±14–28% deviation) lowers peak radiated emissions without filter redesign. |
| Efficiency Optimization | BIAS pin diverts INTVCC current from VIN, reducing input losses-especially beneficial in SEPIC where VOUT < VIN. |
| Robust Protection | Integrated UVLO, overcurrent (3.75A trip), thermal shutdown (>170°C), and SS pin reset on fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC3789EFE#PBF | 4-switch synchronous buck-boost; no integrated switch; requires external MOSFETs and gate drivers. | Supports bidirectional power flow and higher efficiency (>95%) above 1A, but needs larger layout and more components. | Select LTC3789EFE#PBF only when >1A continuous output and highest efficiency are mandatory; LT8362HMSE#TRPBF offers lower component count for <700mA. |
| MAX20404ATPA/VY+ | 3.5V–36V input; 2.5A switch; fixed 2.1MHz frequency; no BIAS pin or SSFM; only boost topology. | Limited to boost-only operation and lacks programmable frequency or multi-topology support. | Choose MAX20404ATPA/VY+ for cost-sensitive, space-constrained boost-only designs where 36V max input suffices and EMI is less critical. |
Compared with LTC3789EFE#PBF and MAX20404ATPA/VY+, the LT8362HMSE#TRPBF uniquely combines topology flexibility (boost/SEPIC/inverting), ultralow 9µA IQ, SSFM, and AEC-Q100 H-grade in one monolithic package-making it optimal for compact, battery-aware, and thermally demanding systems.

FAQ
What is the maximum junction temperature rating for LT8362HMSE#TRPBF?
The LT8362HMSE#TRPBF is rated for operation from –40°C to 150°C junction temperature and is qualified to AEC-Q100 Grade 0. Thermal protection activates above 170°C, forcing shutdown until die temperature falls below the hysteresis threshold. This rating makes LT8362HMSE#TRPBF suitable for under-hood automotive modules and enclosed industrial power supplies where ambient temperatures exceed 105°C.
Can LT8362HMSE#TRPBF generate a negative output voltage?
Yes, the LT8362HMSE#TRPBF supports inverting converter topology using its single FBX pin with a –0.80V internal reference. When configured as an inverting regulator, the feedback divider connects between VOUT and GND, pulling FBX to –0.80V. Amplifier A2 becomes active to provide non-inverting gain from FBX to VC, enabling stable negative output regulation-verified in typical applications like ±15V dual-rail supplies for automotive audio amplifiers.
How does the BIAS pin improve efficiency in LT8362HMSE#TRPBF?
The BIAS pin on LT8362HMSE#TRPBF supplies the INTVCC regulator when 4.4V ≤ BIAS ≤ VIN, diverting up to 1.6mA of bias current away from VIN. In SEPIC applications where VOUT < VIN (e.g., 24V out from 48V input), connecting BIAS to VOUT reduces total input current and improves full-load efficiency by 4–6%. This feature is absent in most competing boost controllers and directly lowers thermal stress on upstream supplies.
What is the minimum on-time specification for LT8362HMSE#TRPBF?
The LT8362HMSE#TRPBF has a minimum on-time of 70ns (typical) in Burst Mode and 60ns (typical) in Pulse-Skip Mode at VIN = 24V. This enables high step-up ratios (e.g., 12V → 48V at 2MHz) while maintaining stable operation in discontinuous conduction mode. The minimum on-time is temperature-stable across –40°C to 150°C, ensuring consistent performance in automotive and industrial environments.
Does LT8362HMSE#TRPBF support external clock synchronization?
Yes, the SYNC/MODE pin of LT8362HMSE#TRPBF accepts an external square-wave clock (20–80% duty cycle, 0.4V–6V swing) to synchronize switching frequency from 300kHz to 2MHz. When synchronized, the LT8362HMSE#TRPBF disables Burst Mode and operates in pulse-skip mode to maintain regulation alignment with the master clock-critical for noise-sensitive applications like RF transceivers and high-speed data acquisition systems.
