Product details

Overview

MP4013BGS-P from Monolithic Power Systems is a high-brightness, high-current-accuracy WLED controller IC designed for constant-current LED driving in 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 fast PWM dimming with deep dimming ratio for LCD backlighting systems.

For engineers reviewing the MP4013BGS-P datasheet, MP4013BGS-P pinout, MP4013BGS-P application, or MP4013BGS-P equivalent, this page provides verified technical context, SOIC-16 package mapping, real-world dimming interface behavior (DC/pulse analog + PWM), protection architecture details (OVP, SCP, OTP, short-LED), and validated alternative part comparisons for backlight driver design.

Technical Context

The MP4013BGS-P implements peak-current-mode control with integrated slope compensation to prevent subharmonic oscillation at duty cycles >0.5. Its error amplifier features 370 µA/V transconductance and COMP pin-based soft-start with 15–30 µA sourcing/sinking current.

It supports dual analog dimming: DC voltage (0–2.34 V on ADIM) linearly scales the 600 mV FB reference, while high-frequency pulse input (on ADIM_P) modulates an internal R-C filtered average voltage on ADIM. PWM dimming disables GATE and pulls DIMO low with synchronized oscillator during low phase.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPQ4013BGLE-A	Automotive-grade AEC-Q100 qualified version; identical electrical specs but extended temp range (−40°C to +125°C) and enhanced ESD immunity	Required for automotive interior lighting where qualification and long-term reliability are mandatory	Select when automotive qualification, higher junction temperature margin, or stricter ESD performance is required
LT3761EFE#PBF	Higher max input (95 V), integrated boost diode, no ADIM_P pin; 600 mV FB reference, ±1.5% accuracy, 100–1000 kHz f_SW	Better suited for high-output-voltage LED strings (>150 V); lacks pulse-analog dimming and has looser FB accuracy	Choose for >150 V LED arrays or when integrated diode simplifies layout, accepting reduced dimming flexibility

Compared with MP4013BGS-P, MPQ4013BGLE-A adds automotive qualification without altering core functionality, while LT3761EFE#PBF trades dimming versatility for higher voltage capability and integrated diode-making each suitable for distinct system-level priorities: qualification rigor versus output voltage headroom.

FAQ

What is the maximum LED string voltage supported by MP4013BGS-P?

The MP4013BGS-P itself does not impose a hard upper limit on LED string voltage; it relies on external components. In typical boost configurations, output voltages up to 150 V are demonstrated with proper MOSFET (e.g., AP18N20GP) and diode (e.g., WUGP20G) selection. The OVP pin allows user-programmable overvoltage threshold up to 5 V reference, enabling safe operation at higher outputs when properly configured.

How does the ADIM_P pin function in pulse analog dimming mode?

ADIM_P accepts a high-frequency pulse signal (>10 kHz recommended). Internally, this signal is conditioned and averaged via an R-C filter on the ADIM pin. The resulting DC voltage on ADIM (0–2.34 V) linearly adjusts the LED current reference. Pulling ADIM_P above 6.9 V disables this mode, reverting to DC analog or PWM-only control.

Can MP4013BGS-P operate in SEPIC topology, and what design changes are needed?

Yes, MP4013BGS-P supports SEPIC topology per its datasheet. Key changes include replacing the boost inductor with coupled inductors or two separate inductors, adding a coupling capacitor between input and switch node, and adjusting compensation network values due to altered power stage transfer function and right-half-plane zero location.

What is the purpose of the UVLO pin, and how is it different from VIN UVLO?

The UVLO pin sets a secondary, user-programmable undervoltage lockout threshold (2.37 V) for the input bus-distinct from the internal VIN UVLO (7.1 V). It allows system-level brownout detection before the IC powers up, enabling graceful shutdown of upstream converters or battery management circuits when bus voltage drops below a safe level.

Does MP4013BGS-P support synchronous rectification?

No, MP4013BGS-P does not integrate or drive a synchronous rectifier. It controls only the main boost/SEPIC switch (via GATE) and an external dimming MOSFET (via DIMO). The freewheeling path requires an external Schottky or fast recovery diode, as shown in the typical application circuit with D1 and D2.

How is short-LED protection triggered and cleared?

Short-LED protection triggers when FB voltage exceeds 1.22 V for ≥1.4 µs-indicating excessive current through the sense resistor. Upon detection, the IC latches off: GATE, DIMO, and COMP are pulled low, and FAULT goes low. Recovery requires cycling EN or VIN; no automatic retry is implemented to prevent repeated stress on failed LED strings.

What is the minimum recommended gate resistor value for GATE pin drive?

A 10–20 Ω gate resistor is recommended between GATE and the external MOSFET gate to dampen ringing and control slew rate. Lower values risk excessive gate current spikes and EMI; higher values slow switching, increasing conduction losses. Layout parasitics and MOSFET Q_g should be considered-typical design uses 15 Ω with 1 nF gate capacitance.
