Product details

Overview

AP6015-33M10G-13 from Diodes Incorporated is a fixed-output 3.3V, 800mA synchronous step-down DC-DC converter in MSOP-10L package, operating from 2.5V to 5.5V input, delivering >94% efficiency at 300mA with 1MHz switching frequency and 150μA quiescent current. It integrates N- and P-channel MOSFETs and supports mobile handset, USB DSL modem, and portable media player power rails.

For engineers reviewing the AP6015-33M10G-13 datasheet, AP6015-33M10G-13 pinout, AP6015-33M10G-13 application, or AP6015-33M10G-13 equivalent, key selection criteria include fixed 3.3V output accuracy (±3%), 1μA shutdown current, internal soft-start, power-good flag, and thermal performance in compact MSOP-10L.

Technical Context

The AP6015-33M10G-13 employs current-mode PWM control with 1MHz oscillator for fast transient response and stable loop behavior across load and line variations. Its integrated synchronous rectification eliminates external diode, reducing conduction loss and enabling high efficiency (>94%) from light-load to full 800mA.

It features under-voltage lockout (1.6V typical), open-drain power-good output with 92% VO threshold and 2.5% hysteresis, and internal soft-start with ~1ms ramp time to prevent inrush current and output overshoot during enable.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.3V ±3% over full temperature and load range - ensures stable rail for 3.3V logic and interface ICs.
Max Output Current	800mA continuous - supports moderate-power subsystems like WLAN modules or camera sensors without external boost.
Input Voltage Range	2.5V to 5.5V - compatible with single-cell Li-ion (fully charged) and dual/triple alkaline/NiMH battery stacks.
Switching Frequency	1MHz typical - enables use of small 3.3μH inductors and 10μF ceramic capacitors, minimizing PCB area.
Quiescent Current	150μA typical - extends battery life in always-on or low-duty-cycle portable devices.
Shutdown Current	≤1μA - critical for long-term storage or deep-sleep modes in handheld electronics.
Efficiency	94% at 5V_IN/3.3V_OUT/300mA - reduces thermal load and improves energy utilization in space-constrained designs.

Pinout & Package

Package: MSOP-10L (3.0mm × 4.9mm, 0.5mm pitch), RoHS-compliant, green molding compound.

Pin/Terminal	Circuit Role	Design Meaning
PVCC	Main power input	Supplies high-side switch and gate driver; requires local 10μF input capacitor.
VCC	Bypass supply	Internal LDO input; must be decoupled with 1μF capacitor adjacent to pin.
GND	Analog ground reference	Reference for error amplifier and bandgap; separate from PGND to minimize noise coupling.
PG	Power-good open-drain output	Asserts when V_OUT ≥ 92% of nominal; requires external pull-up for system sequencing.
FB	Feedback node	Internally connected to fixed 3.3V divider; not user-adjustable in this variant.
CC	Compensation node	Connects external RC network (e.g., 82kΩ + 100pF) to stabilize control loop.
NC	No-connect	Unbonded pin; must remain floating per datasheet.
EN	Enable control input	Active-high logic; pulls low to enter 1μA shutdown mode.
LX	Switching node	Connects to inductor; carries high di/dt current - requires short, wide copper trace.
PGND	Power ground return	High-current return path for MOSFETs and inductor; tied to GND at single point.

Key Features

Feature	Design Value
Synchronous rectification	Integrated N- and P-channel MOSFETs eliminate external Schottky diode, reducing BOM count and conduction loss.
1MHz constant-frequency PWM	Enables predictable EMI filtering and consistent inductor sizing across designs using 3.3μH/10μF standard values.
Internal soft-start	~1ms voltage ramp prevents output overshoot and limits inrush current during power-up sequencing.
Power-good flag with hysteresis	92% VO activation threshold + 2.5% hysteresis ensures reliable system reset and avoids false toggling near regulation limit.
Thermal protection	Junction-to-ambient θ_JA = 161°C/W on 2oz copper PCB - supports operation up to +85°C ambient with minimal heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-output synchronous buck converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP3428WU-7	3.3V fixed, 1A output, 2.5–5.5V input, 1.2MHz f_SW, 25μA I_Q, WLCSP-12 package	Higher current rating and lower quiescent current, but requires ultra-compact layout and has no PG output	Select for space-constrained wearables needing >800mA or sub-50μA I_Q; avoid if PG sequencing or MSOP-10L compatibility is required.
TPS62231DRYR	3.3V fixed, 600mA, 2.05–6.5V input, 3.6MHz f_SW, 17μA I_Q, 6-pin WSON	Higher switching frequency enables smaller passives, but lower max current and no PG or EN polarity flexibility	Choose for high-density designs where 3.6MHz allows <1μH inductors; not suitable for 800mA loads or systems requiring power-good monitoring.

Compared with AP3428WU-7 and TPS62231DRYR, the AP6015-33M10G-13 offers balanced 800mA capability, industry-standard MSOP-10L packaging, integrated PG signaling, and proven 1MHz stability - making it optimal for mid-volume portable electronics where reliability, layout simplicity, and system-level control matter more than minimum size or ultra-low I_Q.

FAQ

What is the recommended input capacitor for AP6015-33M10G-13?

A minimum 10μF X5R/X7R ceramic capacitor must be placed between PVCC and GND, located as close as possible to the PVCC pin. For best performance with 5V input, use two parallel 10μF capacitors - one near PVCC and one near VCC - to suppress high-frequency switching noise and ensure stable startup.

Does AP6015-33M10G-13 require an external feedback resistor network?

No. The AP6015-33M10G-13 is the fixed 3.3V output version; its internal resistor divider connects FB directly to the error amplifier, eliminating external resistors. The FB pin is not user-accessible for adjustment - only used for internal regulation and PG comparator reference.

How does the power-good (PG) signal behave during startup and shutdown?

PG remains high-impedance until EN is asserted high; then it activates after ~100μs, pulling low until V_OUT reaches 92% of 3.3V (≈3.04V), after which it opens-drain pulls high via external pull-up. During shutdown (EN low), PG returns to high-impedance - no leakage or contention occurs.

Can AP6015-33M10G-13 operate with a 2.0V input supply?

No. The absolute minimum input voltage is 2.5V per datasheet Recommended Operating Conditions. At 2.0V, UVLO (1.6V threshold) may allow initial start-up, but the device cannot sustain regulation or deliver rated 800mA output - operation below 2.5V violates specification and risks instability or dropout.
