Product details
Overview
MP2460GJ-P from Monolithic Power Systems is a 45V, 0.6A, 1.7MHz synchronous step-down DC/DC converter in TSOT23-6 package, integrating high-side (420mΩ) and low-side (220mΩ) MOSFETs with current-mode control, 0.8V feedback reference, and 1μA shutdown quiescent current. It delivers regulated power in battery-powered industrial meters and automotive aftermarket systems requiring wide-input operation.
For engineers reviewing the MP2460GJ-P datasheet, MP2460GJ-P pinout, MP2460GJ-P application, or MP2460GJ-P equivalent, key selection criteria include its 4.5–45V input range, 98% max duty cycle for low-dropout operation, hiccup-mode short-circuit protection, internal soft-start, and compatibility with ceramic or electrolytic output capacitors.
Technical Context
The MP2460GJ-P employs fixed-frequency peak-current-mode PWM control at 1.7MHz with automatic light-load pulse-skip mode (PSM) to reduce gate-driving and switching losses. Its internal error amplifier compares FB voltage against a precision 0.8V reference and drives a COMP node that sets switch peak current.
It integrates dedicated bootstrap regulation for the high-side driver, supports pre-biased start-up, and features valley-current sensing during low-side conduction plus peak-current limiting during high-side conduction - enabling robust over-current and short-circuit protection with hiccup recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 45V - supports direct connection to 24V/36V industrial buses and 12V automotive batteries with headroom for load dump transients. |
| Output Current | 0.6A continuous - sufficient for powering microcontrollers, sensors, and communication ICs in compact embedded systems. |
| Switching Frequency | 1.7MHz (±18%) - enables use of small external inductors (e.g., 4.7µH) and reduces EMI filtering requirements. |
| Feedback Reference | 0.8V ±2.5% - allows precise output voltage setting from 0.8V to 0.98×VIN using standard resistor dividers. |
| Quiescent Current | 220µA typical at no load - extends battery life in always-on monitoring devices such as smart meters. |
| Shutdown Current | 2µA maximum - ensures negligible drain during system sleep modes. |
| Thermal Shutdown | 151°C with 21°C hysteresis - provides self-recovery protection without external circuitry under sustained overload. |
Pinout & Package
MP2460GJ-P is housed in a thermally enhanced TSOT23-6 package (0.95mm height, 2.9mm × 1.6mm footprint), optimized for high-power-density PCB layouts with minimal thermal resistance (θJA = 74°C/W on 2-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST | Bootstrap supply for high-side driver | Must be decoupled to SW via 0.1µF ceramic capacitor; enables floating gate drive for integrated high-side MOSFET. |
| GND | Power and signal ground reference | Primary return path for output capacitor and IC bias; requires low-inductance layout adjacent to output capacitor negative terminal. |
| FB | Error amplifier input | Connected to resistor divider tap; regulates output by comparing against internal 0.8V reference; supports remote sensing. |
| EN | Enable control input | Logic-high (>1.55V) enables operation; floating or logic-low disables IC; internal 6V Zener clamp protects against overvoltage. |
| VIN | Main input power supply | Supplies control circuitry, BST regulator, and high-side switch; requires local 4.7µF ceramic decoupling capacitor. |
| SW | Switch node | Internal connection point between high-side source and low-side drain; connects directly to power inductor; high di/dt node requiring tight loop area. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | 420mΩ high-side + 220mΩ low-side MOSFETs eliminate external FETs and gate drivers, reducing BOM count and layout complexity. |
| Light-Load Efficiency Mode | Pulse-skip mode reduces quiescent current to 220µA and eliminates switching losses below ~50mA load, critical for battery longevity. |
| Dedicated Internal Compensation | RC network embedded in error amplifier eliminates need for external compensation components, simplifying design and improving stability across capacitor types. |
| Low-Dropout Operation | 98% max duty cycle and adaptive frequency extension allow stable regulation when VIN approaches VOUT (e.g., 6V→5V), avoiding dropout failure. |
| Robust Protection Suite | Cycle-by-cycle current limit, hiccup-mode SCP, thermal shutdown, and UVLO prevent damage during fault conditions without external supervision. |
Applications
| Power Meters | Aftermarket Automotive |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RT6203BGQW | 36V max input, 0.6A, 1.5MHz, requires external compensation, no BST pin - uses integrated boot diode instead. | Lacks low-dropout mode and hiccup SCP; less tolerant of 45V transients and pre-biased start-up. | Prefer MP2460GJ-P where 45V rating, 98% duty cycle, or hiccup recovery is required. |
| TPS560200 | 17V max input, 0.6A, 600kHz, integrated compensation, 1.2V feedback reference - lower voltage, slower frequency, higher VREF. | Not suitable for >17V inputs; requires larger inductor; incompatible with 0.8V feedback networks. | Select MP2460GJ-P for designs needing >24V input capability or tighter output voltage accuracy below 3.3V. |
Compared with RT6203BGQW and TPS560200, MP2460GJ-P uniquely combines 45V operation, 1.7MHz frequency, 0.8V reference, and hiccup-mode SCP in a 6-pin TSOT23 package - making it optimal for space-constrained, wide-input industrial and automotive power rails.

FAQ
What is the minimum recommended output capacitance for stable operation?
The MP2460GJ-P is stable with ≥4.7µF ceramic or ≥22µF low-ESR electrolytic output capacitors. For 0.1% output ripple in power meter applications, MPS recommends pairing a 22µH inductor with a 470µF electrolytic capacitor and 22µF ceramic capacitor in parallel.
Can MP2460GJ-P operate with an input voltage below 4.5V?
No - the absolute minimum operating input voltage is 4.5V due to VIN UVLO rising threshold of 4.3V (typical). Below this, the device remains disabled. The 1µA shutdown current applies only when EN is pulled low or floated, not during UVLO lockout.
How does the bootstrap capacitor value affect performance?
A 0.1µF X7R ceramic capacitor between BST and SW is mandatory. Insufficient capacitance causes high-side driver undervoltage, leading to erratic switching or complete loss of regulation. Larger values (>0.22µF) offer no benefit and may slow bootstrap recharge during high-duty-cycle operation.
Is MP2460GJ-P compatible with pre-biased outputs?
Yes - the MP2460GJ-P supports monotonic start-up into pre-biased loads. Its internal circuitry refreshes BST voltage and charges the soft-start capacitor based on sensed FB voltage, preventing reverse current flow and ensuring controlled ramp-up even when VOUT is initially non-zero.
What is the maximum achievable output voltage accuracy over temperature?
Feedback voltage is specified as 0.78V to 0.82V over –40°C to +125°C, corresponding to ±2.5% tolerance. Combined with resistor divider tolerance, total output voltage error remains within ±3% across full junction temperature range for properly selected 1% resistors.
Does MP2460GJ-P require an external Schottky diode for bootstrap charging?
No - the MP2460GJ-P integrates a dedicated bootstrap regulator with internal P-channel pass transistor and UVLO protection. External diodes are unnecessary and would degrade efficiency and reliability; only a 0.1µF BST–SW capacitor is required.
How does thermal shutdown behave during sustained overload?
At junction temperature ≥151°C, MP2460GJ-P disables switching and holds output low. Once die temperature falls below 130°C (151°C – 21°C hysteresis), it automatically resumes soft-start and normal regulation - no manual reset or EN toggle is needed.
