Product details
Overview
AP65200MP-13 from Diodes Incorporated is a 340 kHz external-compensated synchronous DC/DC buck converter with integrated 130 mΩ high- and low-side MOSFETs, delivering up to 2 A continuous output current at up to 95% efficiency across 4.7–18 V input range, and featuring automated light-load efficiency improvement for gaming consoles and FPGA power supplies.
For engineers reviewing the AP65200MP-13 datasheet, AP65200MP-13 pinout, AP65200MP-13 application, or AP65200MP-13 equivalent, this device supports adjustable output (0.925–16 V), programmable soft-start, current-mode control for fast transient response, and thermal/overcurrent protection in SO-8EP, MSOP-8EP, and U-DFN2626-10 packages.
Technical Context
The AP65200MP-13 implements fixed-frequency current-mode control with 340 kHz oscillator and internal slope compensation to suppress subharmonic oscillation. Its error amplifier (800 V/V gain, 1000 µA/V transconductance) interfaces externally via COMP pin for loop stabilization using RC network.
It integrates cycle-by-cycle overcurrent protection triggered by high-side MOSFET voltage drop sensing, with fold-back frequency reduction to 102 kHz and 70% current limit when FB drops to 0.3 V. Thermal shutdown activates at 160°C with 40°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.7 V to 18 V - supports wide-input industrial and consumer power rails including 5 V, 12 V, and 18 V supplies. |
| Continuous Output Current | 2 A - delivers stable regulated output under sustained load without derating at +85°C ambient. |
| Switching Frequency | 340 kHz - enables compact magnetics while balancing EMI and efficiency; typical variation ±12% over temperature. |
| Feedback Reference Voltage | 0.925 V ±25 mV - sets output voltage accuracy; used with external resistor divider to configure 0.925–16 V outputs. |
| RDS(ON) (HS & LS) | 130 mΩ each - minimizes conduction loss and enables >95% peak efficiency at 3.3 V/2 A with 12 V input. |
| Soft-Start Current | 6 µA - charges external capacitor to ramp reference from 0 V to 0.925 V; 0.1 µF yields 15 ms startup time. |
| Thermal Shutdown Threshold | 160°C - protects die during overload or poor PCB thermal design; auto-recovery at ~120°C. |
Pinout & Package
AP65200MP-13 is supplied in a RoHS-compliant SO-8EP package with exposed thermal pad (soldered to GND), offering θJA = 40°C/W on 2″×2″ 2 oz copper PCB with thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BS (Pin 1) | Bootstrap Supply Input | Provides gate drive voltage for high-side MOSFET; requires ≥0.01 µF capacitor from SW to BS. |
| IN (Pin 2) | Main Power Input | Accepts 4.7–18 V supply; must be bypassed with bulk capacitor to suppress input ripple and noise. |
| SW (Pin 3) | Switching Node Output | Connects to inductor input; carries high di/dt switching waveform; critical for EMI and layout integrity. |
| GND (Pin 4) | Power Ground | Primary return path for high-current switch node and IC ground; must be low-impedance and tied to thermal pad. |
| FB (Pin 5) | Feedback Input | Senses output voltage via resistive divider; regulates output to 0.925 V reference; sensitive to noise coupling. |
| COMP (Pin 6) | Compensation Node | Output of error amplifier; connects to external RC network to set pole-zero placement for loop stability. |
| EN (Pin 7) | Enable Control | Digital input with 0.7–0.8 V rising threshold and 2.2–2.5 V lockout; 100 kΩ pull-up enables automatic startup. |
| SS (Pin 8) | Soft-Start Control | Accepts external capacitor to linearly ramp reference voltage; floating disables soft-start. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2315DJ-LF-P (Monolithic Power) | 3 A rating, 500 kHz fSW, 80 mΩ RDS(ON), no external COMP pin - uses internal compensation. | Higher current and frequency suit smaller inductors but lacks external loop tuning flexibility for noisy environments. | Select when board space is constrained and loop stability is verified across all load/line conditions without adjustment. |
| TPS54202HDDCR (Texas Instruments) | 2 A, 400–2200 kHz adjustable fSW, 120 mΩ RDS(ON), integrated soft-start and Eco-mode for light loads. | Wider frequency range enables EMI spread-spectrum tuning; Eco-mode differs from AP65200's algorithm in transition behavior and minimum off-time. | Select when EMI compliance requires frequency dithering or when tighter light-load regulation (<±2%) is required. |
Compared with MP2315DJ-LF-P and TPS54202HDDCR, the AP65200MP-13 offers external compensation for robust loop tuning in variable PCB layouts, deterministic 340 kHz switching for predictable filter design, and proven light-load behavior in consumer audio and display systems.

FAQ
What is the recommended input capacitor for AP65200MP-13 at 12 V input and 2 A load?
A minimum 10 µF ceramic capacitor placed close to the IN and GND pins is required; Diodes recommends two 22 µF X5R/X7R MLCCs in parallel for optimal high-frequency decoupling and ripple suppression. Total effective capacitance should exceed 40 µF with ESR <10 mΩ to prevent input voltage sag during load transients.
How does the AP65200MP-13 enter and exit light-load mode?
The IC automatically detects output current via internal current sense circuitry and transitions to light-load mode when load falls below ~200 mA. It exits this mode when current exceeds the same threshold. No external control is needed-mode switching is transparent and maintains regulation within ±1.5% across the full load range.
Can the AP65200MP-13 operate with an output voltage lower than 0.925 V?
No. The internal reference is fixed at 0.925 V, and the feedback comparator is designed to regulate only at or above this voltage. Attempting to set VOUT < 0.925 V results in unregulated operation and potential instability; the minimum valid output is 0.925 V with R2 = 0 Ω and R1 omitted (not recommended for production).
What thermal design guidance applies to the SO-8EP package of AP65200MP-13?
The exposed thermal pad must be soldered to a minimum 80% copper area connected to a solid GND plane with ≥4 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). On a 2″×2″ 2 oz FR-4 board, this achieves θJA = 40°C/W; insufficient pad area or missing vias increase junction temperature by >30°C at full load.
