Product details
Overview
LT7200SAV#TRPBF from Analog Devices is a quad-channel monolithic synchronous buck regulator with Silent Switcher®2 architecture, delivering ±5A per channel (±20A total) across 0.5V–0.9×VIN output range. It operates from 2.9V–18V SVIN and 1.5V–18V PVIN inputs, supports programmable 400kHz–3MHz switching frequency, and achieves up to 96% efficiency in server and FPGA point-of-load applications.
For engineers reviewing the LT7200SAV#TRPBF datasheet, LT7200SAV#TRPBF pinout, LT7200SAV#TRPBF application, or LT7200SAV#TRPBF equivalent, key selection criteria include its AEC-Q100 qualification, 48-lead LQFN package, individual channel tracking/soft-start, ±0.8% reference accuracy over temperature, and phase-lockable multi-phase operation for low-input-capacitor designs.
Technical Context
The LT7200SAV#TRPBF implements a constant-frequency, current-mode control architecture with controlled on-time regulation and internal phase-lock loop synchronization. Its four independent channels support out-of-phase operation via PHMODE pin (GND = 4-phase, INTVCC = 3-phase), reducing input/output ripple and capacitor requirements.
Each channel features individual ITH compensation, programmable DCM/FCM via MODE/SYNC, and dedicated RUN/PGOOD/TRACK/FB pins enabling precise sequencing, fault monitoring, and voltage ramp control. The integrated Silent Switcher®2 architecture embeds bypass capacitors and minimizes PCB layout sensitivity for ultralow EMI compliance.

Pinout & Package
LT7200SAV#TRPBF is housed in a low-profile 5mm × 6mm 48-lead LQFN package with exposed thermal pad for enhanced heat dissipation. Pin assignments are validated per Analog Devices' Rev. 2 datasheet (pages 8–10).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PHMODE | Phase configuration control | Selects 4-phase (GND) or 3-phase (INTVCC) interleaving to minimize input/output ripple |
| MODE/SYNC | Operating mode & clock sync | GND = DCM; floating/≥1V = FCM; external clock = synchronized FCM with ±30% capture range |
| PVIN1–PVIN4 | Per-channel power input | Independent high-side MOSFET supply inputs-enables mixed-voltage input domains |
| SW1–SW4 | Per-channel switch node | Connects to external inductor; voltage swing spans GND to PVINx - requires low-inductance layout |
| FB1–FB4 | Per-channel feedback input | Regulates to 0.5V reference; sets VOUT = 0.5V × (1 + R2/R1) - supports wide output range |
| TRACK1–TRACK4 | Per-channel soft-start/tracking | Internal 5µA pull-up enables capacitor-based soft-start or external voltage tracking for rail sequencing |
| PGOOD1–PGOOD4 | Per-channel power-good status | Open-drain output pulled low if FBx deviates >±7.5% from 0.5V - enables system-level fault isolation |
| RUN1–RUN4 | Per-channel enable control | Logic-high (>1.16V) activates channel; hysteresis prevents chatter during power ramp |
| ITH1–ITH4 | Per-channel error amplifier output | Controls valley current limit threshold linearly (0.3V–1.6V); supports internal or external compensation |
| RT | Frequency programming | Connects to GND via RRT (33.2kΩ–249kΩ) to set fSW = 0.4–3MHz - enables EMI tuning |
| SVIN | Signal input supply | Filtered input to internal 5V regulator; bypassed with 1µF ceramic - decouples noise from control circuitry |
| INTVCC | Internal 5V regulator output | Powers gate drivers and logic; requires ≥4.7µF low-ESR ceramic to ground - critical for stability |
| GND | Power/signal ground | Multiple pins (2,3,12,13,26,27,36,37) - must be connected to low-impedance thermal pad for thermal performance |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC3310S | Single-channel 10A monolithic buck; no multi-phase or PHMODE control; smaller 3mm × 4mm package | Not suitable for quad-rail systems; requires four devices for equivalent channel count | Choose LTC3310S only when space-constrained single-rail design dominates over system-level integration |

FAQ
What is the maximum output current per channel for the LT7200SAV#TRPBF?
The LT7200SAV#TRPBF delivers ±5A per channel, supporting bidirectional current flow for dynamic load transients. This is confirmed in the datasheet's Features section and Table 1 (ILIM-POS = +5A to +7A, ILIM-NEG = –5.8A to –7.9A). Total system output capability is ±20A across all four channels, making LT7200SAV#TRPBF suitable for high-current FPGA and ASIC core rails.
Does the LT7200SAV#TRPBF support automotive qualification?
Yes, the LT7200SAV#TRPBF is AEC-Q100 qualified for automotive applications, as explicitly stated in the Rev. 2 datasheet's Features section and Revision History (page 4). This qualification covers stress testing and reliability validation for operation in harsh automotive environments, including under-hood ADAS domain controllers where LT7200SAV#TRPBF is deployed.
How is switching frequency programmed on the LT7200SAV#TRPBF?
Switching frequency on the LT7200SAV#TRPBF is programmed using an external resistor (RRT) connected between the RT pin and GND. Per Table 1 and Figure 23, RRT values from 33.2kΩ to 249kΩ set fSW from 3MHz down to 400kHz. The LT7200SAV#TRPBF also supports external clock synchronization via the MODE/SYNC pin with ±30% capture range, enabling noise-sensitive system-level timing alignment.
What package type does the LT7200SAV#TRPBF use?
The LT7200SAV#TRPBF uses a 5mm × 6mm 48-lead LQFN package with exposed thermal pad, as specified in the datasheet's Features section and Outline Dimensions (page 35). This package provides low thermal resistance and high power density, essential for dissipating heat from ±20A total output current in compact server and telecom PCB layouts where LT7200SAV#TRPBF is commonly applied.
Can the LT7200SAV#TRPBF operate in both DCM and FCM modes?
Yes, the LT7200SAV#TRPBF supports both Discontinuous Conduction Mode (DCM) and Forced Continuous Conduction Mode (FCM) via the MODE/SYNC pin: tie to GND for DCM (high efficiency at light loads), leave floating or tie ≥1V for FCM (low-noise, fast transient response). This dual-mode capability is documented in the Features list and MODE/SYNC pin description (page 9), allowing designers to optimize LT7200SAV#TRPBF for either efficiency or performance based on application needs.
