PRODUCT OVERVIEW

What Is the LTC3787MPUFD#TRPBF?

LTC3787MPUFD#TRPBF is a high performance PolyPhase® single output synchronous boost converter controller from Analog Devices that drives two N-channel power MOSFET stages out-of-phase. Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors than the single-phase equivalent.

Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, enabling high power boost applications. A 4.5V to 38V input supply range encompasses a wide range of system architectures and battery chemistries. When biased from the output of the boost converter or another auxiliary supply, the LTC3787 can operate from an input supply as low as 2.5V after start-up.

The operating frequency can be set for a 50kHz to 900kHz range or synchronized to an external clock using the internal PLL. PolyPhase operation allows the LTC3787 to be configured for 2-, 3-, 4-, 6- and 12-phase operation. The SS pin ramps the output voltage during start-up. The PLLIN/MODE pin selects Burst Mode® operation, pulse-skipping mode or forced continuous mode at light loads.

The LTC3787MPUFD#TRPBF is the MP-grade version in a thermally enhanced 28-lead QFN package with an exposed pad, tested and guaranteed over the full –55°C to +150°C operating junction temperature range. The device is RoHS compliant (ROHS3), REACH unaffected, and in active production.

2-Phase PolyPhase Operation Drives two N-channel MOSFET stages out-of-phase, reducing input and output capacitor requirements and allowing smaller inductors.

Wide V_IN and High V_OUT 4.5V to 38V input range (40V absolute maximum), operates down to 2.5V after start-up, with output voltage up to 60V.

–55°C to +150°C MP-Grade Tested and guaranteed over the full –55°C to +150°C operating junction temperature range for military and harsh industrial applications.

DESIGN REFERENCE

Circuit Considerations for LTC3787MPUFD#TRPBF

Frequency, Phase & Mode Configuration

The LTC3787MPUFD#TRPBF offers flexible frequency and mode configuration:

Switching Frequency (FREQ Pin): An external resistor from FREQ to GND programs the switching frequency from 50kHz to 900kHz. When the PLLIN/MODE pin is driven by an external clock, the internal PLL synchronizes the switching frequency to the external clock from 75kHz to 850kHz.
Phase-Lockable Frequency: The internal PLL allows the switching frequency to be phase-locked to an external clock from 75kHz to 850kHz.
Light Load Mode Selection (PLLIN/MODE Pin): Selects Burst Mode® operation, pulse-skipping mode, or forced continuous mode at light loads. Burst Mode® operation achieves the lowest quiescent current of 135µA.
Soft-Start (SS Pin): An external capacitor on the SS pin ramps the output voltage during start-up, controlling the inrush current.
Current Sensing (SENSE+/SENSE– Pins): Supports either R_SENSE resistor or inductor DCR current sensing for flexible current limit programming.
PolyPhase Configuration: Phase modulation enables configuration for 2-, 3-, 4-, 6-, and 12-phase operation for higher power applications.

PCB and System-Level Guidance

Boost controller performance depends on layout and component selection:

Input Capacitors: Place low-ESR ceramic input capacitors close to the V_IN and PGND pins to minimize input ripple and supply noise.
Inductor Selection: Multiphase operation allows the use of smaller inductors than the single-phase equivalent. Select based on output current, ripple, and switching frequency.
Gate Drive Supply (INTV_CC): The internal LDO powers the gate drive from VBIAS or EXTV_CC. Decouple INTV_CC to PGND with a low-ESR ceramic capacitor.
Exposed Pad: The exposed thermal pad on the QFN package must be soldered to the PCB ground plane for optimal thermal performance. Thermal resistance θ_JA is 43°C/W for the QFN package.
Junction Temperature Calculation: T_J = T_A + (P_D × θ_JA), where θ_JA = 43°C/W for the QFN package.
Verify the recommended PCB footprint from the official datasheet prior to production.
