Product details
Overview
MP163BGSE-5-Z from Monolithic Power Systems is a 700V non-isolated offline primary-side regulator with integrated 700V MOSFET and 5V LDO, supporting buck/boost/flyback topologies for dual-output CV regulation without optocoupler. It delivers up to 4W output power, achieves <30mW no-load consumption, and features green-mode operation with frequency foldback and peak-current compression. Used in home appliance standby power supplies.
For engineers reviewing the MP163BGSE-5-Z datasheet, MP163BGSE-5-Z pinout, MP163BGSE-5-Z application, or MP163BGSE-5-Z equivalent, key selection criteria include its SOIC16 package, 420mA peak current limit, 14Ω RDS(on), thermal shutdown at 150°C, and LDO enable control via EN pin - all critical for low-power offline AC/DC design.
Technical Context
The MP163BGSE-5-Z implements primary-side constant-voltage (CV) control using feedback sampling from a capacitor-based hold circuit referenced to a 2.55V internal error amplifier threshold. Its green-mode operation dynamically reduces both switching frequency and peak current under light load, enabling <30mW no-load power draw.
It integrates a 700V vertical DMOS power switch with 14Ω typical RDS(on), an internally biased VCC supply with UVLO (5.1–5.8V turn-on), and a dedicated 5V LDO with 150mA continuous output and 270mA OLP-limited peak current. Protection includes OLP (220ms delay), SCP (600mA threshold), open-loop detection (<0.5V FB), and thermal shutdown with 30°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | Up to 700V HV drain rating enables direct universal AC rectified input connection without external HV transistor. |
| Peak Current Limit | 420mA typical - sets maximum energy per cycle in buck/boost topologies; defines max output power with inductor selection. |
| MOSFET RDS(on) | 14Ω typical at 25°C - determines conduction loss and thermal rise in high-side switch applications. |
| LDO Output | 5.0V ±2% at 0A, 620–1100mV dropout at 150mA - powers auxiliary logic or MCU rails from main converter output. |
| No-Load Power | <30mW - meets Energy Star Level VI and EU CoC Tier 2 standby requirements for white goods. |
| Protection Features | Thermal shutdown (150°C), VCC UVLO (5.1–5.8V), OLP (220ms delay), SCP (600mA), open-loop detection (FB <0.5V). |
| Package | SOIC16 - provides 1.56W power dissipation capability (θJA = 80°C/W) and 7 exposed pads for thermal relief. |
Pinout & Package
MP163BGSE-5-Z is housed in a 16-pin SOIC package with exposed thermal pad. Pin 15 is IN (LDO input), Pin 11 is SOURCE (MOSFET source and system ground reference), Pin 8 is DRAIN (700V HV node), Pin 9 is VCC (internal bias rail), Pin 10 is FB (2.55V reference feedback), Pins 1/4/14 are GND (LDO ground), Pin 3 is OUT (5V LDO output), Pin 16 is EN (active-high LDO enable), and Pins 2/5/6/7/12/13 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 15 (IN) | LDO input | Accepts 4.3–17V DC input; voltage drop across internal pass element determines LDO thermal load. |
| Pin 11 (SOURCE) | MOSFET source / system ground | Serves as return path for HV switch, VCC, and FB; must be low-inductance ground plane connection. |
| Pin 8 (DRAIN) | HV MOSFET drain | Connects directly to rectified AC line; withstands 700V transient spikes; requires snubber for flyback/buck-boost. |
| Pin 9 (VCC) | Internal bias supply | Charged by internal HV regulator; UVLO (5.1–5.8V) controls startup; discharges to 2.8V during fault recovery. |
| Pin 10 (FB) | CV regulation feedback | Monitors sampled output via RC network; triggers switching when below 2.55V; open-loop protection at <0.5V. |
| Pin 3 (OUT) | LDO output | Delivers regulated 5V; limited to 150mA continuous; drops out at 620–1100mV under full load. |
| Pin 16 (EN) | LDO enable | Active-high logic input (1.32–1.64V threshold); pulls LDO into shutdown mode drawing only 3–9µA. |
Key Features
| Feature | Design Value |
|---|---|
| Primary-side CV regulation | Eliminates optocoupler and secondary-side TL431, reducing BOM count and improving reliability in cost-sensitive appliances. |
| Integrated 700V MOSFET + LDO | Reduces external component count by ≥4 devices (HV FET, gate driver, LDO IC, decoupling caps) in dual-rail offline designs. |
| Green-mode frequency foldback | Switching frequency drops below 28kHz at light load, minimizing core loss and EMI while maintaining <30mW no-load consumption. |
| Programmable OLP delay | 220ms fixed delay prevents false triggering during startup transients while ensuring robust overload cutoff. |
| Thermal shutdown with hysteresis | Shuts down at 150°C junction temperature and recovers at 120°C, preventing thermal cycling damage in enclosed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar offline primary-side regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP163BGS-5-Z | Same electrical specs but in SOIC8-7B package; lower thermal dissipation (1.45W vs. 1.56W) and higher θJA (86°C/W). | Preferred for space-constrained PCBs where thermal budget allows; not suitable for >3W continuous output. | Select when board area is critical and output power ≤2.5W; verify thermal performance with layout simulation. |
| MP163CGSE-5-Z | Higher 660mA peak current limit and 13.5Ω RDS(on); supports up to 4W output with improved efficiency at full load. | Required for higher-power applications like induction cooktop control or multi-rail appliance boards. | Choose when designing for >3.5W output or tighter efficiency targets; expect slightly higher no-load consumption due to larger MOSFET. |
Compared with MP163BGS-5-Z, MP163BGSE-5-Z offers superior thermal handling in SOIC16 for sustained 4W operation, while MP163CGSE-5-Z trades marginally higher no-load draw for enhanced full-load capability - making MP163BGSE-5-Z the optimal balance for mainstream 3–4W appliance standby designs.

FAQ
What is the maximum continuous output power achievable with MP163BGSE-5-Z in buck topology?
The MP163BGSE-5-Z supports up to 4W continuous output power in buck configuration under proper thermal management. This is validated with SOIC16 package (1.56W PD), 420mA peak current limit, and 14Ω RDS(on). At 230VAC input and 12V/200mA + 5V/50mA dual output, measured efficiency exceeds 78% at full load per MPS Typical Application data.
Does MP163BGSE-5-Z require an external optocoupler for regulation?
No. MP163BGSE-5-Z uses primary-side constant voltage (CV) regulation with internal sampling capacitor feedback, eliminating the need for optocoupler, secondary-side shunt regulator, or transformer auxiliary winding. Regulation accuracy is ±5% over line/load/temperature per datasheet specifications.
How does the EN pin affect system-level power sequencing?
The EN pin (Pin 16) provides active-high logic control of the integrated 5V LDO only - it does not disable the main HV regulator. When EN is low, LDO output shuts down drawing just 3–9µA, while the main converter continues switching if VCC remains above UVLO. This enables independent logic rail control without disrupting main power delivery.
Can MP163BGSE-5-Z operate in flyback topology with primary-side regulation?
Yes. MP163BGSE-5-Z explicitly supports flyback topology per datasheet description and block diagram. It regulates output voltage by sampling reflected voltage across the primary winding via a resistor divider to FB pin, using the same 2.55V reference and timing-controlled on/off strategy as in buck mode.
What is the minimum recommended dummy load for stable no-load regulation?
A 3mA dummy load is recommended to ensure sufficient inductor energy for reliable sampling capacitor charging and accurate CV regulation at no-load. This value is derived from MPS application guidance to maintain FB voltage stability when output current falls below 5mA, especially critical for <30mW no-load designs.
How does thermal shutdown recovery work after junction temperature exceeds 150°C?
When junction temperature exceeds 150°C, MP163BGSE-5-Z halts switching and discharges VCC to 2.8V via internal 16–24µA current source. Recovery begins only after VCC falls below VCCpro (2.4–2.8V) and junction temperature drops to 120°C, providing 30°C hysteresis to prevent thermal oscillation in poorly ventilated enclosures.
Is the SOIC16 package of MP163BGSE-5-Z lead-free and RoHS-compliant?
Yes. MP163BGSE-5-Z is fully lead-free, halogen-free, and compliant with EU RoHS Directive 2011/65/EU. All MPS parts undergo rigorous quality assurance per ISO 9001 and AEC-Q200 stress testing; green status documentation is available on the Monolithic Power Systems website.
