Product details

Overview

AP1662MTR-G1 from Diodes Incorporated is a high-performance active power factor correction (PFC) controller IC designed for DCM boundary conduction mode operation in electronic ballasts, AC-DC adapters, and off-line SMPS. It integrates a one-quadrant multiplier, zero-current detector, totem-pole gate driver (600mA source / 800mA sink), 2.5V ±1% reference, and IEC61000-3-2 compliance at full load with THD <10%.

For engineers reviewing the AP1662MTR-G1 datasheet, AP1662MTR-G1 pinout, AP1662MTR-G1 application, or AP1662MTR-G1 equivalent, key selection criteria include boundary-mode PFC control architecture, ZCD-based MOSFET turn-on timing, OVP/UVLO protection thresholds, and SO-8 thermal performance under 90W PFC operation.

Technical Context

The AP1662 implements a current-mode DCM boundary conduction controller using zero-current detection to trigger MOSFET turn-on and a multiplier-driven current sense comparator to terminate each switching cycle. Its error amplifier regulates output voltage via a 2.5V internal reference, with dynamic OVP triggered by >40μA current into COMP and static OVP at VCOMP <2.25V.

Functional blocks include a BiCMOS-based starter timer (75–300μs), UVLO with 2.5V hysteresis (11V ON / 9.5V OFF), and a clamped totem-pole output stage capable of driving 11N65C3 MOSFETs. The ZCD input disables the IC when pulled below 150mV, reducing quiescent current to 20–90μA.

Key Specifications

Parameter	Value and Actual Design Meaning
V_REF	2.5V ±1% @ +25°C - enables precise output voltage regulation in PFC feedback loop
I_START-UP	40μA typical - allows high-value start-up resistor for low standby loss
I_Q	2.5mA typical - minimizes power dissipation in continuous operation
IOVP	40μA typical - fast dynamic over-voltage protection via COMP pin current sensing
V_ZCD-T	1.6V negative-going threshold - ensures accurate zero-current turn-on timing
I_GD-SOURCE/I_GD-SINK	600mA / 800mA - drives high-V_DS MOSFETs like 11N65C3 without external buffer
V_CS-CLAMP	1.7V typical - limits peak inductor current during startup or overload
THD	<10% at high line/full load - meets IEC61000-3-2 Class C requirements

Pinout & Package

AP1662MTR-G1 is housed in an SO-8 package (6.2mm × 5.1mm × 1.75mm), optimized for thermal dissipation in 90W PFC applications with R_θJA = 150°C/W at T_A = +50°C.

3 MULT	Multiplier AC voltage input	Accepts rectified line signal (0–3.5V); shapes current waveform to match voltage sine
4 CS	Current sense comparator input	Compares sensed MOSFET current against multiplier output; terminates switch on-threshold
5 ZCD	Zero-current detection input	Detects auxiliary winding voltage drop to enable boundary-mode turn-on; disables IC if <150mV
6 GND	Power and signal ground	Common return for gate driver, control logic, and current sense path

Equivalent & Alternatives

The following parts are listed as comparable options for similar active PFC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AL6562A	Higher start-up current (75μA vs. 40μA); no internal OVP current sensing; requires external OVP circuit	Lacks dynamic OVP; needs additional components for IEC61000-3-2 compliance at full load	Select AL6562A only for cost-sensitive designs where external OVP is acceptable and THD margin >15%
ICE3PCS01G	Fixed-frequency CCM controller; 65kHz operation; integrated 600V startup circuit; no ZCD pin	Requires different inductor design; not suitable for boundary-mode or low-THD LED drivers	Choose ICE3PCS01G for higher-power (>150W) CCM PFC where size constraints favor fixed frequency

Compared with AL6562A and ICE3PCS01G, AP1662MTR-G1 uniquely combines ZCD-based boundary-mode control, integrated dynamic OVP, and ultra-low start-up current-making it optimal for compact, low-THD, single-stage PFC designs up to 90W.

FAQ

What is the purpose of the ZCD pin on AP1662MTR-G1?

The ZCD (Zero Current Detection) pin monitors auxiliary winding voltage to detect inductor current zero-crossing, triggering MOSFET turn-on in boundary conduction mode. When ZCD voltage falls below 1.6V (negative-going edge), the gate driver activates. Pulling ZCD below 150mV disables the IC, reducing quiescent current to 20–90μA for fault recovery or standby.

How does the AP1662MTR-G1 achieve IEC61000-3-2 compliance?

AP1662MTR-G1 meets IEC61000-3-2 Class C through DCM boundary-mode control, which shapes input current to closely follow the AC voltage waveform. Its one-quadrant multiplier, precise 2.5V reference, and low-THD design ensure <10% total harmonic distortion at full load and high line voltage without external compensation.

Can AP1662MTR-G1 drive a 650V MOSFET directly?

Yes-the totem-pole gate driver delivers 600mA source and 800mA sink current, sufficient to drive common 650V superjunction MOSFETs (e.g., 11N65C3) with minimal external components. Output clamp voltage is 9–13V at VCC=20V, ensuring robust gate overvoltage protection during transients.

What is the function of the COMP pin beyond error amplification?

Beyond amplifying feedback error, the COMP pin serves as the dynamic OVP input: excess current (>40μA) flowing into COMP from the feedback capacitor triggers immediate shutdown. It also provides upper (5.55V) and lower (2.25V) clamps to limit multiplier input range and prevent saturation during transient events or overvoltage conditions.
