Product details
Overview
LT8607EDC#TRMPBF from Analog Devices is a 42V, 750mA synchronous step-down regulator in an 8-lead 2mm × 2mm DFN package, featuring 2.5µA quiescent current in Burst Mode, 35ns minimum on-time, and internal compensation for fast transient response. It delivers regulated 3.3V or adjustable output in automotive and industrial power systems with wide input range (3.0V–42V).
For engineers reviewing the LT8607EDC#TRMPBF datasheet, LT8607EDC#TRMPBF pinout, LT8607EDC#TRMPBF application, or LT8607EDC#TRMPBF equivalent, key selection criteria include ultralow IQ at light load, fixed Burst Mode operation (no SYNC pin), thermal performance in DFN-8, EMI reduction via inherent low ripple, and AEC-Q100 qualification for automotive use.
Technical Context
The LT8607EDC#TRMPBF implements peak current mode control with internal 0.778V feedback reference and fixed Burst Mode operation-SYNC is internally grounded per datasheet, eliminating external clock synchronization or spread spectrum capability. Its 35ns minimum on-time enables high VIN/VOUT ratios (e.g., 42V→3.3V) at 2MHz switching.
Thermal design relies on the exposed GND pad (Pin 9), with θJA = 102°C/W; it integrates overtemperature protection and ±8.5% power-good monitoring referenced to FB voltage. The DFN package omits TR/SS and SYNC pins, disabling soft-start programming and external frequency control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 42V - supports 12V/24V/36V automotive and industrial rails without pre-regulation. |
| Quiescent Current (Burst Mode) | 2.5µA typical - enables >10-year battery life in always-on telematics or sensor nodes. |
| Max Continuous Output Current | 750mA - sufficient for powering microcontrollers, CAN transceivers, and analog front-ends. |
| Switching Frequency Range | 200kHz to 2.2MHz (RT-programmable) - allows optimization of inductor size vs. efficiency (e.g., 4.7µH @ 2MHz). |
| Feedback Reference Voltage | 0.778V (±12mV over temp) - sets output accuracy for adjustable configurations using external resistor divider. |
| Minimum On-Time | 35ns - enables high step-down ratios (e.g., 42V→3.3V) at 2MHz without pulse-skipping instability. |
| Power-Good Threshold | ±8.5% of FB voltage - provides reliable rail validation for downstream logic reset sequencing. |
Pinout & Package
LT8607EDC#TRMPBF uses an 8-lead plastic DFN package (2mm × 2mm), with exposed thermal pad (Pin 9) soldered to PCB ground for thermal management (θJA = 102°C/W). No SYNC or TR/SS pins are present - Burst Mode is fixed and soft-start is internal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST | Bootstrap supply for high-side NMOS gate drive | Requires 0.1µF ceramic capacitor to SW; no series resistor allowed. |
| SW | Switch node connecting internal FETs to inductor | High di/dt node; must be minimized on PCB to reduce EMI and switching loss. |
| INTVCC | Internal 3.5V regulator output | Bypass with ≥1µF low-ESR ceramic; not for external loading. |
| RT | Resistor-to-ground sets oscillator frequency | Supports 200kHz–2.2MHz; value determines inductor size and efficiency trade-off. |
| EN/UV | Enable and input undervoltage lockout input | 1.05V rising threshold; used to shut down at VIN < 3.2V or enable with external divider. |
| VIN | Main input power supply | Must be locally bypassed with low-ESR capacitor placed adjacent to VIN/GND pins. |
| PG | Open-drain power-good indicator | Pulled low when FB is within ±8.5% of 0.778V and EN/UV is high; requires external pull-up. |
| FB | Feedback input for adjustable output regulation | Regulated to 0.778V; connects to resistor divider tap - defines VOUT = 0.778V × (1 + R1/R2). |
| GND | Power and signal ground (exposed pad) | Exposed pad (Pin 9) must be soldered to PCB ground plane for thermal and electrical integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ Burst Mode | 2.5µA typical input current at no load enables multi-year operation from coin cells in IoT sensors. |
| Fixed Burst Mode Operation | No SYNC pin - eliminates layout complexity and ensures consistent low-ripple, low-IQ behavior across all units. |
| 35ns Minimum On-Time | Enables direct 42V→3.3V conversion at 2MHz without requiring cascaded regulators or external FETs. |
| AEC-Q100 Qualified | Rated for –40°C to +125°C junction temperature - validated for automotive infotainment, ADAS camera modules, and body control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8607IDC#TRMPBF | Same DFN-8 package and Burst Mode operation; rated for –40°C to 125°C (same temp grade as LT8607EDC#TRMPBF) | Identical functionality and pinout; differs only in screening/test grade (I-grade vs E-grade) | Select LT8607IDC#TRMPBF if extended production test coverage or higher reliability screening is required for mission-critical designs. |
| LT8607BDC#TRMPBF | Same DFN-8 package but operates in pulse-skipping mode (no Burst Mode); higher light-load IQ (~hundreds of µA) | Suitable where deterministic switching (e.g., for EMI spectral shaping) or faster light-load transient response is prioritized over ultralow IQ | Choose LT8607BDC#TRMPBF only when Burst Mode's variable frequency is undesirable and higher quiescent current is acceptable. |
Compared with LT8607EDC#TRMPBF, LT8607IDC#TRMPBF offers identical electrical and thermal performance with enhanced test coverage, while LT8607BDC#TRMPBF trades ultralow IQ for deterministic pulse-skipping behavior - making LT8607EDC#TRMPBF optimal for battery-sensitive automotive and industrial applications demanding lowest possible standby power.

FAQ
What is the quiescent current of the LT8607EDC#TRMPBF in Burst Mode operation?
The LT8607EDC#TRMPBF draws 2.5µA typical quiescent current in Burst Mode at no load, with 3.0µA typical in a full application circuit. This ultralow IQ is achieved by shutting down internal control circuitry between energy pulses, making LT8607EDC#TRMPBF ideal for battery-backed systems like automotive parking cameras and wireless sensors.
Does the LT8607EDC#TRMPBF support external frequency synchronization?
No, the LT8607EDC#TRMPBF does not support external synchronization. As a DFN-package variant, it has no SYNC pin - the SYNC function is internally grounded, fixing operation in Burst Mode only. For sync capability, select the MSOP-packaged LT8607MSE#TRPBF instead of LT8607EDC#TRMPBF.
What is the maximum output current capability of the LT8607EDC#TRMPBF?
The LT8607EDC#TRMPBF delivers up to 750mA of continuous output current under thermal limits defined by its DFN-8 package and PCB layout. Derating applies above +85°C ambient; at 125°C junction temperature, output current is reduced to maintain safe operation. Peak current limit is 1.7A (typical) per electrical characteristics table.
Is the LT8607EDC#TRMPBF qualified for automotive applications?
Yes, the LT8607EDC#TRMPBF is AEC-Q100 qualified for automotive applications, rated for operation from –40°C to +125°C junction temperature. It is specified for use in automotive subsystems including camera modules, telematics units, and body electronics where reliability under temperature cycling, vibration, and voltage transients is critical - confirming LT8607EDC#TRMPBF's suitability for production automotive designs.
How is the output voltage set on the LT8607EDC#TRMPBF?
The LT8607EDC#TRMPBF uses an adjustable feedback architecture: output voltage is set by an external resistor divider connected between VOUT and GND, with the FB pin tied to the divider midpoint. The IC regulates FB to 0.778V, so VOUT = 0.778V × (1 + R1/R2). For example, R1 = 187kΩ and R2 = 100kΩ yields ~2.25V; precision 1% resistors are recommended to maintain accuracy across temperature.
