Product details
Overview
AP2001SL-13 from Diodes Incorporated is a monolithic dual-channel PWM controller IC designed for DC/DC converter and backlight inverter power-supply regulation. It integrates two error amplifiers, adjustable oscillator (up to 500 kHz), dead-time control (0–100%), under-voltage lockout (UVLO: 2.45–2.65 V), short-circuit protection (SCP), and 2.5 V reference output in SOP-16L package.
For engineers reviewing the AP2001SL-13 datasheet, AP2001SL-13 pinout, AP2001SL-13 application, or AP2001SL-13 equivalent, this device supports dual-output buck/boost topologies with externally driven CE-output transistors, precise timing via RT/CT, and robust fault protection for industrial and computing power supplies.
Technical Context
The AP2001SL-13 implements dual independent PWM channels with common oscillator and shared reference, each featuring dedicated error amplifier inputs (EA1±/EA2±), feedback pins (FB1/FB2), and dead-time control inputs (DTC1/DTC2). Its oscillator frequency is set by external RT (5.1–100 kΩ) and CT (150–15,000 pF), supporting 1–500 kHz operation with ±2% temperature stability.
UVLO ensures outputs remain disabled until VCC exceeds 2.65 V, while SCP latches off both outputs upon detection of overcurrent at the FB pin (threshold: 0.65–0.75 V). The 2.5 V reference (±1% accuracy, ±7.5 mV load regulation) feeds internal comparators and supports external circuit biasing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel PWM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UC3846N | Single-ended output architecture; no integrated dead-time control; requires external DTC circuitry | Designed for single-output forward/flyback; lacks dual independent FB inputs and REF output | Choose when only one regulated output is needed and external timing components are acceptable |
| TL5001CP | Single-channel PWM; no dead-time control; 2.5 V reference only; max fOSC = 500 kHz but no DTC or dual FB | Targeted at basic boost/buck converters; not suitable for dual-output or bridge-driven topologies | Use where cost sensitivity outweighs dual-channel functionality and fault protection requirements |
Compared with UC3846N and TL5001CP, the AP2001SL-13 uniquely integrates dual independent feedback paths, per-channel dead-time control, and a buffered 2.5 V reference-enabling compact, robust dual-output designs without external support circuitry.

FAQ
What is the maximum allowable supply voltage for AP2001SL-13?
The absolute maximum VCC rating is 40 V, with recommended operating range of 3.6 V to 40 V. Exceeding 40 V risks permanent damage to internal circuitry, including the reference bandgap and output transistors. Operation below 3.6 V triggers UVLO, disabling outputs until voltage recovers above 2.65 V.
Can AP2001SL-13 drive MOSFET gates directly?
No-it provides open-collector common-emitter (CE) pre-driver outputs rated for 90 mA short-circuit current and 2 V saturation voltage at 10 mA. These require external gate drivers or discrete transistor buffers to safely switch power MOSFETs; direct connection risks slow switching, shoot-through, and thermal overstress.
How is oscillator frequency adjusted on AP2001SL-13?
Oscillator frequency is set by external RT (5.1–100 kΩ) and CT (150–15,000 pF) components connected to pins 14 and 1, respectively. Frequency ranges from 1 kHz to 500 kHz; typical values like RT = 10 kΩ and CT = 330 pF yield ~200 kHz. Temperature and supply voltage variation is ±2% across operating conditions.
Does AP2001SL-13 include built-in short-circuit protection for both channels?
Yes-SCP is implemented per channel via FB1 and FB2 pins, with threshold of 0.65–0.75 V. When either FB pin exceeds this, the corresponding output (OUT1 or OUT2) is latched off. The global SCP pin (pin 16) enables or disables this function; floating or pulling high activates protection, pulling low disables it.
