Product details

Overview

MP4013GS-P from Monolithic Power Systems is a high-brightness, high-current-accuracy WLED controller IC designed for constant-current LED driving in boost, buck, buck-boost, and SEPIC topologies. It operates from 8V–26V input, delivers ±1.2% LED current regulation via 600mV FB reference, supports programmable switching frequency (112–670 kHz), and integrates 5V ±1% reference output. Used in LCD backlighting with fast deep PWM dimming up to 10,000:1 ratio.

For engineers reviewing the MP4013GS-P datasheet, MP4013GS-P pinout, MP4013GS-P application, or MP4013GS-P equivalent, key selection criteria include its SOIC-16 package, cycle-by-cycle OCP via CS pin, dual analog dimming (DC/pulse), fault-indicating open-drain FAULT pin, and integrated protections including OVP, SCP, OTP, and short-inductor/diode detection.

Technical Context

The MP4013GS-P implements peak-current-mode control with internal slope compensation to prevent subharmonic oscillation at duty cycles >0.5. Its error amplifier features 370 µA/V transconductance and soft-start current limiting (15–30 µA) to manage inrush during startup.

It supports three dimming methods: DC analog dimming (0–2.34V on ADIM), pulse-input analog dimming (via ADIM_P with RC filtering), and external PWM dimming (on PWM pin), with DIMO providing dedicated gate drive for external dimming MOSFETs. The FAULT pin pulls low on latch-off faults including short LED, OVP, and COMP saturation timeout.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	8V–26V - powers internal regulator and enables wide-range industrial/bus-supply compatibility.
FB Reference Voltage	600 mV ±1.2% - sets LED current accuracy via external R_FB; enables <1% current tolerance in production designs.
REF Output	5 V ±1% - supplies stable bias for external circuitry (e.g., ADC references, sensor biasing).
Switching Frequency	112–670 kHz - programmable via RT resistor; balances EMI, efficiency, and magnetics size.
Dimming Support	DC analog (ADIM), pulse analog (ADIM_P), and PWM (PWM pin) - enables flicker-free, high-ratio (>10,000:1) brightness control.
OVP Threshold	5.0 V on OVP pin - triggers shutdown when output overvoltage exceeds programmed threshold (e.g., open-circuit LED string).
Fault Response	Latch-off with FAULT pin pulled low - ensures fail-safe shutdown for short LED, short output, OCP, and thermal events.

10 DIMO	External dimming MOSFET driver	13.3V output; sinks 0.2A / sources 0.1A; controls series dimming FET in LED string path.
11 ADIM_P	Pulse analog dimming input	Accepts >10kHz pulse signal; internally filtered to generate average ADIM voltage for linear dimming.
12 ADIM	Analog dimming control input	0–2.34V DC input linearly scales LED current reference; >2.4V disables dimming.
13 COMP	Loop compensation node	Connects RC network for stability; also serves as soft-start capacitor node (1/4 current until 80% I_LED).
14 FB	Current sense feedback	600mV reference; connects to R_FB from LED cathode to GND; >1.22V for 1µs triggers short-LED protection.
15 OVP	Overvoltage protection monitor	5.0V threshold; resistor divider from LED+ sets OVP point ~10–20% above nominal V_OUT.

Equivalent & Alternatives

The following parts are listed as comparable options for similar WLED controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LT3761EFE#PBF	Higher max input (95V), no integrated 5V REF, requires external V_REF; ±2% LED current accuracy.	Preferred for ultra-high-V_OUT (>200V) automotive headlamp drivers; lacks analog dimming flexibility.	Select when >100V output capability is required and system-level reference is already available.
TPS61165DRVR	Fixed 1.2MHz f_SW, no RT pin; only PWM dimming (no analog); 650mV FB reference; SOIC-8 package.	Suitable for compact, cost-sensitive portable displays; limited to boost-only and lower current (<100mA).	Choose for space-constrained consumer displays where deep PWM suffices and analog dimming is unnecessary.

Compared with LT3761EFE#PBF and TPS61165DRVR, MP4013GS-P uniquely combines programmable frequency, dual analog dimming, integrated 5V reference, and SOIC-16 layout margin-making it optimal for industrial and automotive LCD backlight systems demanding design flexibility and long-term supply stability.

FAQ

What topologies does MP4013GS-P support, and how is topology selection implemented?

The MP4013GS-P supports boost, buck, buck-boost, and SEPIC configurations through external component selection-not internal configuration bits. Topology is determined by the external power stage: boost uses inductor-to-input and diode-to-output; buck places inductor between switch node and LED; buck-boost and SEPIC require coupled inductors or transformer windings. No reprogramming or pin strapping is needed-the controller's current-mode architecture adapts inherently.

How does the MP4013GS-P achieve 10,000:1 PWM dimming ratio without visible flicker?

It combines three techniques: (1) oscillator synchronization to the PWM signal to eliminate beat frequencies, (2) fast DIMO turn-off (<100ns) and GATE disable to halt current flow instantly, and (3) internal EA disconnection during low PWM phase to hold COMP voltage and prevent loop instability. This preserves regulation integrity across ultra-low duty cycles (e.g., 0.01%), eliminating low-frequency ripple that causes perceptible flicker.

Can the 5V REF output power external circuitry, and what is its load limit?

Yes-the 5V REF output delivers ±1% accuracy and supports up to 500µA load while maintaining regulation (0–50mV load regulation). It is intended for biasing low-power analog circuits such as op-amps, ADC references, or comparator hysteresis networks. For loads >500µA, an external buffer or LDO is required to avoid reference droop and compromised LED current accuracy.

What happens during a short-LED condition, and how is recovery handled?

When LED+ shorts to GND, FB senses near-zero voltage, causing COMP to saturate. After 2048 consecutive switching cycles in saturation with FB <30% of I_REF, the IC latches off and pulls FAULT low. Recovery requires cycling EN or VIN-there is no auto-restart. This ensures safety-critical systems remain disabled until fault root cause is addressed, preventing repeated stress on power components.

Is the MP4013GS-P pin-compatible with earlier MP4013 variants like MP4013GS?

Yes-MP4013GS-P is a drop-in replacement for MP4013GS in SOIC-16 packaging, sharing identical pinout, electrical specifications, and thermal characteristics. The "-P" suffix denotes tape-and-reel packaging with enhanced moisture sensitivity level (MSL) handling per J-STD-020; no schematic or layout changes are required for migration.

How is overvoltage protection (OVP) configured, and what is its response time?

OVP is configured via a resistor divider from LED+ to the OVP pin, setting trip threshold at 5.0V. When OVP pin voltage reaches 5.0V, the IC immediately disables GATE and DIMO, pulls FAULT low, and latches off. Propagation delay from OVP threshold crossing to FAULT assertion is ≤2µs, verified under worst-case conditions (V_IN=24V, T_J=125°C).

Does MP4013GS-P support spread-spectrum frequency modulation (SSFM) to reduce EMI?

No-MP4013GS-P uses fixed-frequency operation with programmable center frequency via RT resistor, but does not implement SSFM. EMI reduction is achieved instead through clean gate drive (40ns rise/fall), integrated leading-edge blanking, and support for external synchronization (EN/SYNC pin) to align switching edges across multiple controllers and cancel beat frequencies.
