Product details

Overview

IR3513ZMTRPBF from Infineon Technologies is a single-phase XPHASE3™ POL control IC with integrated 7V/2A high-side and 4A sink low-side gate drivers, differential remote sense amplifier (100 kΩ input impedance), and programmable 250 kHz–1.5 MHz per-phase switching frequency via ROSC resistor. It supports 0.8 V to 5.1 V output with ±0.5% system set-point accuracy and implements open-loop protection, OVP, and dynamic margining (±5%). Used in server VRMs and telecom power modules.

For engineers reviewing the IR3513ZMTRPBF datasheet, IR3513ZMTRPBF pinout, IR3513ZMTRPBF application, or IR3513ZMTRPBF equivalent, key selection considerations include its daisy-chain phase timing interface (PHSIN/PHSOUT/CLKOUT), VCCL-regulated bias supply, ROSC-programmed oscillator, and dual over-voltage detection paths (OVSNS and ROSC/OVP).

Technical Context

The IR3513ZMTRPBF operates as a master controller in multi-phase POL architectures, coordinating up to X phases via dedicated PHSOUT→PHSIN daisy-chain timing and CLKOUT-driven synchronization. Its internal gate drivers support bootstrap synchronous PFET operation between BOOST and VCCP pins, enabling efficient high-side drive without external charge pumps.

It integrates three independent protection subsystems: (1) OVP via ROSC/OVP pin (1.6 V threshold), (2) system-level OVP communicated over IIN to Phase ICs, and (3) remote sense line integrity monitoring using VOSEN+/VOSEN− comparators. The EAOUT error amplifier features 100–120 dB DC gain and 20–40 MHz bandwidth for tight regulation loop response.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage Range	0.8 V to 5.1 V; enables direct regulation of core, memory, and I/O rails in modern processors.
System Set-Point Accuracy	±0.5%; ensures precise voltage delivery under load transients and thermal drift.
Switching Frequency Range	250 kHz to 1.5 MHz per phase; programmed by ROSC resistor (7.75–50 kΩ), eliminating need for external clock sources.
Remote Sense Input Impedance	100 kΩ typical; minimizes loading on feedback traces while supporting long-distance sensing in high-current systems.
GATEL Sink Current	4 A peak; drives low-side MOSFET gates directly without external buffers in high-current single-phase designs.
OVP Detection Threshold	1.6 V on ROSC/OVP pin; triggers fast shutdown (<300 ns propagation) upon overvoltage, protecting downstream loads.
VCCL Regulator Output	Programmable 4.75–7.5 V; powers internal clock, comparators, and logic, decoupled from main VCC rail.

Pinout & Package

IR3513ZMTRPBF uses a thermally enhanced 32-lead MLPQ package (5 mm × 5 mm body, 0.5 mm pitch) with exposed thermal pad for improved power dissipation in high-density VRM layouts.

Pin/Terminal	Circuit Role	Design Meaning
GATEH (Pin 1)	High-side gate driver output	Drives N-channel MOSFET gate; rated for 34 V max, 3 A pulsed, with non-overlap logic referenced to SW.
BOOST (Pin 2)	Bootstrap supply for GATEH	Internally connected via synchronous PFET to VCCP; eliminates external diode/capacitor in bootstrap circuit.
VCCP (Pin 3)	Low-side gate driver supply	Provides 7.5 V max supply for GATEL; powers internal PFET connecting to BOOST.
GATEL (Pin 4)	Low-side gate driver output	Sinks 4 A peak to drive synchronous rectifier; referenced to PGND with 0.4 Ω sink resistance.
CSIN+ / CSIN− (Pins 7–8)	Differential current sense inputs	Interface with external shunt or DCR sensing network; includes hiccup-mode OCSET programming and SR disable logic.
PHSOUT / PHSIN / CLKOUT (Pins 26–27, 25)	Daisy-chain phase timing interface	Enables scalable multi-phase coordination: PHSOUT clocks next IC's PHSIN; CLKOUT drives all Phase ICs' CLKIN at aggregate frequency.
ROSC/OVP (Pin 23)	Oscillator programming & OVP monitor	Resistor sets switching frequency; voltage >1.6 V indicates overvoltage fault, triggering immediate shutdown.

Key Features

Feature	Design Value
Scalable phase architecture	Supports 1-to-X phase deployment with only one IC per phase-no separate controller + driver chips required.
Integrated bootstrap PFET	Eliminates external bootstrap diode and capacitor, reducing BOM count and PCB area in compact VRMs.
Dual OVP detection	Independent ROSC/OVP pin and IIN-based communication provide redundant overvoltage protection across master and slave ICs.
Open remote sense line detection	Monitors VOSEN+ and VOSEN− voltages to detect broken sense connections before regulation failure occurs.
Dynamic margining	MARGIN pin shifts VREF ±5% via tri-state input, enabling in-system functional testing without hardware modification.

Equivalent & Alternatives

The following parts are listed as comparable options for similar POL control applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR35203MTRPBF	Two-phase controller with integrated drivers; supports up to 4 phases via daisy chain; higher integration, no external ROSC needed.	Designed for higher-current, space-constrained multi-phase VRMs where board area is premium.	Select when scaling beyond single-phase or requiring tighter layout integration than IR3513ZMTRPBF allows.
UCC28220DR	Single-phase controller without integrated drivers; requires external high/low-side drivers; fixed 300 kHz–1 MHz frequency range.	Used in cost-sensitive industrial supplies where driver flexibility and discrete component selection are prioritized.	Select when driver optimization (e.g., SiC/GaN compatibility) or BOM cost control outweighs integration benefits.

Compared with IR35203MTRPBF, the IR3513ZMTRPBF offers lower gate driver integration but greater design flexibility for custom phase scaling; versus UCC28220DR, it delivers higher accuracy, faster transient response, and built-in protection-justifying its use in mission-critical telecom and server power.

FAQ

What is the function of the ROSC/OVP pin?

The ROSC/OVP pin serves dual roles: (1) a resistor to LGND sets the oscillator frequency (250 kHz–1.5 MHz), and (2) voltage exceeding 1.6 V signals an overvoltage condition, forcing immediate shutdown. During normal operation, the pin sits at 0.6 V, providing real-time fault monitoring without additional components.

How does the IR3513ZMTRPBF handle remote sense line faults?

It detects open remote sense lines using two independent comparators: VOSEN+ comparator triggers if voltage falls below 87.5% of VCCL, and VOSEN− comparator activates if voltage exceeds 0.44 V. Both paths feed into open-loop protection, pulling PG low within 8 PHSOUT pulses to halt regulation safely.

Can the IR3513ZMTRPBF operate as a standalone single-phase regulator?

Yes-it functions as a complete single-phase POL controller with integrated gate drivers, current sensing interface, remote sense amplifier, and protection circuitry. No companion Phase ICs are required unless expanding to multi-phase operation via PHSIN/PHSOUT daisy chain.

What is the purpose of the VCCL regulator and its associated pins?

The VCCL regulator provides a stable 4.75–7.5 V supply for internal clock, comparators, and logic. VCCLFB sets output voltage via resistor divider; VCCLDRV controls external transistor for higher-current bias; and VCCL pins (14, 28) require local decoupling to LGND for noise immunity and startup reliability.
