Product details
Overview
MP024GS-10-Z from Monolithic Power Systems is a primary-side, constant-current/constant-voltage (CC/CV) flyback regulator with integrated 700V MOSFET and high-voltage start-up current source. It delivers accurate output regulation without optocoupler or secondary feedback, supports programmable cable compensation, operates in DCM with variable off-time control, and achieves <30mW no-load power consumption for offline 5V/2A battery chargers.
For engineers reviewing the MP024GS-10-Z datasheet, MP024GS-10-Z pinout, MP024GS-10-Z application, or MP024GS-10-Z equivalent, this page provides verified technical context, SOIC8-7B package mapping, real-world CC/CV operation details, protection behavior under OLP/OTP/OVP, and design-meaning specifications for adapter-level power supply validation.
Technical Context
The MP024GS-10-Z implements primary-side regulation via auxiliary winding voltage sampling at FB, using variable off-time peak-current control to modulate switching frequency between 75Hz and 54kHz. Its internal ZCD circuit detects zero-current crossing with 55–145mV threshold to enforce DCM operation and prevent CCM-induced instability.
It integrates a 700V/4.5Ω MOSFET with thermal shutdown at 140°C and hysteresis of 40°C, plus a programmable cable compensation path via CP pin that sinks current into FB proportional to VCP - enabling dynamic output voltage adjustment up to 4V on CP when configured with a 1µF capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBRDSS | 700V - Withstands full AC line surges up to 265VAC without external clamping. |
| RDS(on) | 4.5Ω typical - Enables efficient 10W adapter operation at 5V/2A with minimal conduction loss. |
| VFB | 3.96V ±60mV - Reference accuracy enables ±1% CV regulation across temperature and load. |
| fS-min | 75Hz - Low-frequency limit reduces audible noise and EMI during light-load conditions. |
| IHV | 2.2mA typical - High-voltage start-up current source charges VCC rapidly from DRAIN without auxiliary winding dependency. |
| PNO-LOAD | <30mW - Meets Energy Star Level VI and EU CoC Tier 2 standby power requirements. |
| VDCM | 100mV typical - ZCD threshold ensures reliable DCM detection even with transformer leakage variation. |
| tONmax | 40μs - Hard limit prevents runaway current during sensing-resistor short or overload. |
Pinout & Package
MP024GS-10-Z is housed in a SOIC8-7B package - an industry-standard 8-pin surface-mount outline with 7 functional pins and 1 non-connected pad (Pin 3), optimized for thermal dissipation in open-frame adapters.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Samples auxiliary winding voltage to regulate output; triggers OVP at 5.96V and OLP at 1.4V. |
| 2 GND | Power ground reference | Common return for internal MOSFET source, current sense, and protection comparators. |
| 4 DRAIN | High-voltage MOSFET drain | Connects to primary winding; supplies internal HV start-up current source and withstands 700V transients. |
| 5 SOURCE | MOSFET source terminal | Connects to current-sense resistor (RS) for peak-current-mode control in both CV and CC modes. |
| 6 SS | Sampling time select | Configures FB sampling duration (1.1–4.9μs) via external resistor to match transformer turn ratio and diode drop. |
| 7 CP | Cable compensation control | Accepts 1µF capacitor to generate VCP; enables programmable voltage droop compensation up to 4V for USB cable loss correction. |
| 8 VCC | Supply rail input | Powered by HV current source until VCCH = 19.4V; shuts down below VCCL = 8.7V to prevent brownout operation. |
Key Features
| Feature | Design Value |
|---|---|
| Primary-side CC/CV regulation | Eliminates optocoupler, TL431, and secondary feedback components - reduces BOM count by ≥4 parts and PCB area by >25%. |

| Integrated 700V MOSFET | Enables single-chip flyback solution for universal-input (85–265VAC) adapters without external HV switch or driver. |
| Variable switching frequency | Naturally spreads EMI spectrum - meets EN55022 Class B conducted emissions without Y-cap or common-mode choke in low-power designs. |
| Full protection suite | Includes OVP, OTP, OLP, SSP, OCkP, and VCC UVLO - ensures robust field reliability in unattended consumer charging applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar primary-side CC/CV flyback regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP023GS-10-Z | Lacks programmable cable compensation; fixed 0.4 DS-Max; no CP pin functionality. | Suitable only for fixed-output adapters without cable drop compensation requirement. | Select when cost sensitivity outweighs need for dynamic voltage adjustment. |
| INN3265C-H201 | Includes integrated X-cap discharge, active startup, and higher integration (X-cap discharge, soft-start); no HV current source. | Requires auxiliary winding for startup; better suited for high-volume OEM designs needing safety certification support. | Choose for designs requiring IEC 62368-1 compliance documentation and integrated safety features. |
Compared with MP024GS-10-Z, MP023GS-10-Z sacrifices cable compensation for lower unit cost, while INN3265C-H201 adds safety-related integration but increases BOM complexity and eliminates HV start-up autonomy - making MP024GS-10-Z optimal for cost-sensitive, self-starting, cable-compensated 5–10W adapters.

FAQ
What is the maximum continuous output power of MP024GS-10-Z at 230VAC?
The MP024GS-10-Z delivers up to 13W in open-frame configurations at 230VAC ±15%, limited by thermal shutdown at 150°C junction temperature. In enclosed non-ventilated adapters, maximum continuous power drops to 10W due to reduced heat dissipation - confirmed per datasheet Table 1 under 50°C ambient conditions.
How does the CP pin enable cable compensation?
The CP pin accepts a 1µF ceramic capacitor to generate a DC voltage (VCP) proportional to output current. This voltage controls internal current sinking into the FB node, adjusting the upper resistor's effective value in the feedback divider - thereby increasing output voltage to offset cable IR drop, with up to 4V compensation range.
Can MP024GS-10-Z operate without an auxiliary winding?
No - the auxiliary winding is required for both CV regulation (via FB sampling) and post-startup VCC supply. The internal HV current source only charges VCC during initial startup; once VCCH is reached, the auxiliary winding takes over to sustain operation and enable precise regulation.
What protection features trigger hiccup mode?
OLP (128-cycle FB < 1.4V), OVP (FB > 5.96V), OCkP (no FB sampling per cycle), SSP (tONmax exceeded), and OTP (junction > 140°C) all force immediate shutdown and enter hiccup mode - cycling on/off until fault condition clears, preventing thermal damage or sustained overvoltage stress.
Is the SOIC8-7B package RoHS and halogen-free?
Yes - MP024GS-10-Z complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21, with lead-free matte tin plating on all terminals. Full green status documentation is available on the MPS Quality Assurance website.
How is switching frequency modulated in CV mode?
In CV mode, the MP024GS-10-Z varies switching frequency from 75Hz to 54kHz based on FB voltage: lower FB voltage (light load) increases off-time to reduce frequency and minimize no-load loss; higher FB voltage (heavy load) decreases off-time to raise frequency and maintain regulation.
What is the purpose of the SS pin?
The SS pin selects FB sampling duration (1.1–4.9μs) via external resistor to align sampling timing with the end of secondary diode conduction - ensuring accurate VAUX measurement despite diode forward-voltage variation across load and temperature.
