Product details
Overview
MP1470HGJ-Z from Monolithic Power Systems is a synchronous step-down DC/DC converter with integrated 110mΩ high-side and 57mΩ low-side MOSFETs, delivering up to 2A continuous output current across a 4.5V–16V input range, fixed 1MHz switching frequency in CCM mode, internal AAM light-load power-save, and 0.804V feedback reference voltage - deployed in compact 6-pin TSOT23-6 packages for space-constrained consumer power rails.
For engineers reviewing the MP1470HGJ-Z datasheet, MP1470HGJ-Z pinout, MP1470HGJ-Z application, or MP1470HGJ-Z equivalent, this page delivers verified technical context on its current-mode control architecture, bootstrap gate drive requirements, thermal shutdown (150°C), hiccup-mode over-current protection, and EN pin logic thresholds - all critical for stable 3.3V/2A or 5V/2A point-of-load designs in digital entertainment systems.
Technical Context
The MP1470HGJ-Z employs current-mode control with an internal error amplifier comparing FB voltage against a precise 0.804V reference, generating COMP voltage to regulate peak inductor current per cycle. Its proprietary AAM (Advanced Asynchronous Modulation) enables pulse-skipping at light loads while maintaining regulation via VAAM voltage comparison.
It operates across three modes: AAM (light load), DCM (medium load), and CCM (full 2A load), with automatic transition based on inductor current zero-crossing detection. The internal 5V regulator powers control circuitry across full VIN range, and the floating bootstrap driver uses external BST capacitor + optional diode for high-duty-cycle (>65%) operation at 3.3V/5V outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 16V - supports 5V, 12V, and 15V system rails without external pre-regulation. |
| Output Current | 2A continuous - sufficient for powering SoCs, FPGAs, or DDR memory I/O in game consoles and STBs. |
| Switching Frequency | Fixed 1MHz in CCM - enables use of small 3.3µH inductors and reduces EMI filtering complexity. |
| Feedback Reference | 0.804V ±12mV - sets output voltage via external resistor divider; enables 1.05V–5V programmability. |
| Internal MOSFET RDS(on) | 110mΩ (HS) / 57mΩ (LS) - minimizes conduction loss at 2A, supporting >90% efficiency at 12V→3.3V/2A. |
| Soft-Start Time | 1.5ms - prevents output overshoot during startup into pre-biased loads or capacitive banks. |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects die under sustained overload or poor PCB thermal design. |
Pinout & Package
MP1470HGJ-Z is housed in a thermally enhanced 6-pin TSOT23-6 package (JEDEC MO-193 AB), with exposed pad for improved heat dissipation and strict coplanarity ≤0.10mm. Pin 1 is bottom-left when viewing top marking left-to-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power ground reference | Primary return path for output current and internal regulator; requires direct low-impedance copper pour connection. |
| 2 SW | Switch node | Drives external inductor; carries high dv/dt switching waveform - must be routed wide and away from analog traces. |
| 3 IN | Main input supply | Accepts 4.5V–16V; requires local 10µF ceramic decoupling capacitor placed adjacent to pin. |
| 4 FB | Feedback input | Senses output voltage via resistor divider; internal 0.804V reference enables precise VOUT programming. |
| 5 EN | Enable control | Active-high digital input (1.5V typical rising threshold); internal 1MΩ pull-down allows float-to-disable. |
| 6 BST | Bootstrap supply | Provides floating gate drive for high-side MOSFET; requires 1µF capacitor between BST and SW pins. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Power MOSFETs | 110mΩ HS + 57mΩ LS - eliminates external switch selection and layout complexity for 2A buck designs. |
| AAM Light-Load Mode | Proprietary pulse-skipping below ~100mA - maintains >85% efficiency at 1mA load without external bias circuits. |
| Integrated Soft-Start | 1.5ms internal ramp - ensures monotonic VOUT rise into pre-biased outputs, preventing reverse current flow. |
| Hiccup Over-Current Protection | FB <140mV triggers periodic restart - limits average short-circuit current to <100mA, reducing thermal stress during fault. |
| Bootstrap UVLO | 2.2V rising threshold with 150mV hysteresis - prevents high-side driver misfire during BST capacitor discharge. |

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 |
|---|---|---|---|
| MP1477H | Successor with improved efficiency (up to 95%), lower quiescent current (25μA vs 0.83mA), and extended input range (4.5V–28V). | Supports higher input voltages and longer battery runtime in portable devices; pin-compatible but requires updated BST capacitor layout. | Select MP1477H for new designs requiring >28V input tolerance or ultra-low IQ in always-on subsystems. |
| TPS562201 | TI part with 4.5V–17V input, 2A output, 500kHz–1.7MHz adjustable frequency, and different EN threshold (1.22V). | Lacks AAM mode; uses forced PWM at light load - higher no-load IQ (25μA) but better noise predictability in EMI-sensitive audio paths. | Choose TPS562201 where deterministic switching frequency and minimal conducted EMI are prioritized over light-load efficiency. |
Compared with MP1470HGJ-Z, MP1477H offers broader input capability and lower standby power, while TPS562201 trades AAM flexibility for frequency programmability and tighter EMI control - making MP1470HGJ-Z optimal for cost-sensitive, space-constrained 12V-input consumer electronics where its proven AAM performance is validated.

FAQ
What is the maximum recommended output current for MP1470HGJ-Z under continuous operation?
The MP1470HGJ-Z is rated for 2A continuous output current at ambient temperatures ≤85°C with proper PCB thermal design (≥2 sq-in 2-oz copper pour). At 125°C junction temperature, derating begins at ~1.5A due to thermal shutdown activation at 150°C - actual usable current depends on input voltage, output voltage, and airflow.
Can MP1470HGJ-Z operate with an input voltage below 4.5V?
No - the absolute minimum input voltage is 4.5V per datasheet specifications. Below this, the internal UVLO circuit disables operation to prevent unstable regulation. The rising UVLO threshold is 4.15V with 340mV hysteresis, meaning the device remains off until VIN exceeds 4.49V after a dropout event.
Is an external bootstrap diode required for MP1470HGJ-Z?
An external bootstrap diode is optional and only beneficial when duty cycle exceeds 65% (e.g., 12V→5V or 12V→3.3V). It improves BST capacitor charging efficiency and reduces losses. For most 12V→3.3V/5V designs, the internal bootstrap charger suffices with a 1µF ceramic capacitor between BST and SW pins.
How does the MP1470HGJ-Z handle pre-biased output conditions during startup?
The MP1470HGJ-Z supports monotonic startup into pre-biased outputs via its internal soft-start circuit. When FB voltage exceeds the rising SS voltage, the controller sequentially enables high-side and low-side switches - preventing reverse current flow and ensuring controlled VOUT ramp-up without overshoot or latch-up.
What is the purpose of the 140mV threshold on the FB pin?
The 140mV FB threshold triggers hiccup-mode over-current protection during output short circuits. When FB drops below this level, the oscillator frequency folds back and the device enters periodic restart cycles - limiting average short-circuit current to ~100mA and preventing thermal runaway without requiring external fault latching circuitry.
Does MP1470HGJ-Z require external compensation components?
No - the MP1470HGJ-Z features an optimized internal compensation network compatible with standard 3.3µH–10µH inductors and ceramic output capacitors. External compensation is unnecessary for stable operation across its full load and input range, reducing BOM count and layout sensitivity.
Why is the MP1470HGJ-Z marked "Not Recommended for New Designs"?
MPS designates MP1470HGJ-Z as legacy due to the introduction of MP1477H, which offers superior specs: wider 4.5V–28V input range, lower 25μA quiescent current, improved thermal performance, and enhanced light-load efficiency. MP1470HGJ-Z remains fully supported for existing designs and legacy replacements.
