Product details
Overview
LV58061MX-TLM-H from SANYO Semiconductor (now ON Semiconductor) is a single-channel step-down switching regulator IC with integrated 0.13Ω high-side MOSFET, delivering up to 3A output current, fixed 370kHz switching frequency, and 0.8V reference voltage. It operates from 8–28V input, achieves 90% efficiency at 1A/5V output, and features thermal shutdown, pulse-by-pulse over-current protection, and soft-start control via external capacitor.
For engineers reviewing the LV58061MX-TLM-H datasheet, pinout, applications, or equivalent options, key selection considerations include its MFP8 (200mil) exposed-pad package, current-mode control architecture, EN pin logic thresholds (1.9V high / 0.8V low), and FB pin bias current (10–100nA) for precision feedback network design.
Technical Context
This Bi-CMOS regulator uses current-mode PWM control with internal 370kHz oscillator and built-in 5V internal regulator for gate drive and bias. The BOOT pin enables high-side FET drive via external 0.01μF bootstrap capacitor, while the COMP pin supports Type II/III compensation networks for stable loop response across load transients.
Protection functions are hardware-based and fully integrated: thermal shutdown triggers at 160°C (40°C hysteresis), over-current limit is set at 4A peak (VIN=12V, VOUT=5V, L=10μH), and UVLO ensures startup only above VIN > ~6.5V. Standby mode draws ≤70μA via EN pin assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 8–28V - supports automotive battery-supplied systems with cold-crank margin |
| Output current capability | 3A continuous - enabled by 0.13Ω high-side FET and exposed-pad thermal path |
| Switching frequency | 370kHz (typ) - balances EMI, inductor size, and efficiency for mid-power DC/DC |
| Reference voltage | 0.8V ±2% - sets output via resistor divider; enables 3.3V, 5V, or custom outputs |
| Efficiency | 90% at 1A/5V (VIN=12V) - reflects conduction + switching losses under real operating conditions |
| Standby current | ≤70μA - allows ultra-low-power system sleep states without external disconnect |
| Thermal shutdown | 160°C junction, 40°C hysteresis - prevents latch-up and enables safe auto-recovery |
Pinout & Package
MFP8 (200mil) package with exposed thermal pad - 8-pin surface-mount, 5.0×4.4mm body, 1.7mm max height, optimized for PCB heat spreading on 2-layer boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: BOOT | Bootstrap supply node | Connects 0.01μF capacitor to SW; enables high-side FET gate drive above VIN |
| 2: VIN | Main power input | Accepts 8–28V; requires ≥20μF bulk capacitance to GND for stability |
| 3: SW | Power switch node | Drives external LC filter; connects to BOOT cap and inductor; handles pulsed 3A+ currents |
| 4: GND | Power and signal reference | Common return for all internal circuits; must be tied to exposed pad for thermal performance |
| 5: FB | Feedback input | Senses output voltage via resistor divider; 10–100nA bias current minimizes divider error |
| 6: EN | Enable control | Active-high logic: ≥1.9V enables, ≤0.8V disables; 16μA pull-up simplifies open-drain interface |
| 7: COMP | Loop compensation | Connects external RC network to stabilize control loop against load/transient variations |
| 8: SS | Soft-start timing | 10μA internal current source charges external capacitor; sets ramp time (e.g., 0.015μF = 1.2ms) |
Key Features
| Feature | Design Value |
|---|---|
| Integrated high-side FET | 0.13Ω RDS(on) reduces conduction loss and eliminates external MOSFET layout complexity |
| Current-mode control | Enables fast load transient response and simplifies compensation vs. voltage-mode topologies |
| Exposed thermal pad | Supports 2.05W allowable dissipation on specified 46.4×31.8mm² board - critical for 3A operation |
| Pulse-by-pulse OCP | Hardware-limited 4A peak current per cycle prevents inductor saturation and MOSFET failure |
| Fixed-frequency oscillator | 370kHz operation enables predictable EMI filtering and consistent inductor sizing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2315DJ-LF-Z | 400kHz switching, 3.5A rating, no exposed pad, different pinout (8-pin SOIC) | Lacks thermal pad; lower Pd max (1.5W); requires larger heatsinking at full load | Choose when board space permits SOIC and thermal budget allows derating |
| TPS54331DR | Adjustable frequency (100–2500kHz), 3A, integrated compensation, different package (SOIC-8) | No BOOT/SW separation; uses integrated high-side FET but lacks dedicated boot capacitor node | Prefer when programmable frequency or simplified layout outweighs fixed 370kHz stability |
Compared with MP2315DJ-LF-Z and TPS54331DR, the LV58061MX-TLM-H offers superior thermal performance via its exposed-pad MFP8 package and deterministic 370kHz operation-critical for noise-sensitive applications where EMI filtering must target a known frequency band.

FAQ
What is the maximum input voltage rating for LV58061MX-TLM-H?
The LV58061MX-TLM-H has an absolute maximum input voltage of 32V on the VIN pin. This rating includes margin for transient spikes; designers must ensure coil-induced surges and load-dump events do not exceed this limit even momentarily. Operation is specified from 8V to 28V under recommended conditions, making LV58061MX-TLM-H suitable for 12V and 24V automotive and industrial systems.
How does the soft-start function work on LV58061MX-TLM-H?
The LV58061MX-TLM-H implements soft-start via an internal 10μA current source connected to the SS pin. An external capacitor (e.g., 0.015μF) is charged linearly to the 0.8V reference, controlling output voltage ramp time. For LV58061MX-TLM-H, this yields a typical 1.2ms soft-start period, preventing inrush current into downstream capacitors and reducing stress on input sources and power switches.
What package type and thermal characteristics does LV58061MX-TLM-H use?
LV58061MX-TLM-H uses the MFP8 (200mil) package with an exposed thermal pad. On a specified 46.4×31.8mm² two-layer board, it achieves 2.05W allowable power dissipation. The exposed pad must be soldered to a thermal copper area to realize this rating; insufficient thermal relief will cause premature thermal shutdown at high load currents.
Can LV58061MX-TLM-H operate with an output voltage lower than 3.3V?
Yes - LV58061MX-TLM-H supports any output voltage ≥0.8V using the FB pin and external resistor divider. Since the internal reference is fixed at 0.8V ±2%, setting VOUT = 1.2V requires R1/R3 = 0.5 (e.g., R1 = 10kΩ, R3 = 20kΩ). Accuracy depends on resistor tolerance and FB pin bias current (10–100nA), so 1% resistors are recommended for <1% output error.
Does LV58061MX-TLM-H include over-current protection, and how is it implemented?
Yes, LV58061MX-TLM-H features pulse-by-pulse over-current protection that limits peak switch current to 4A under typical conditions (VIN=12V, VOUT=5V, L=10μH). This is sensed internally on the high-side FET and resets each cycle. Unlike latch-off schemes, this allows continued operation during brief overload events while protecting the IC and external components from destructive current levels.
