ACT4088US-T 4.5-40V Input 2.5A Continuous Output 93% Efficiency 300kHz Frequency Low 30μA IQ Integrated Protections AEC-Q100 Qualified Thermally

ACT4088US-T 4.5-40V Input 2.5A Continuous Output 93% Efficiency 300kHz Frequency Low 30μA IQ Integrated Protections AEC-Q100 Qualified Thermally Enhanced TSSOP Package

Features

1. Wide Input Voltage Range (4.5V to 40V)

Supports input voltages up to 40V, capable of withstanding load dump and voltage surges common in automotive environments. Compatible with 12V/24V systems and suitable for industrial power applications.

2. High Output Current Capability (2.5A Continuous)

Delivers up to 2.5A of continuous output current, directly driving medium-to-high-power loads (e.g., motors, LED arrays, processor cores) without external current-expansion components.

3. High Efficiency (93% Peak)

Utilizes synchronous rectification technology (with low on-resistance MOSFETs) to minimize switching losses, maintaining high efficiency even under medium-to-high loads and reducing thermal management needs.

4. Low Quiescent Current (30μA)

Operates with only 30μA quiescent current under light-load or standby conditions, significantly reducing power consumption in battery-powered or always-on systems (e.g., automotive continuous power systems).

5. High Switching Frequency (300kHz)Fixed 300kHz switching frequency enables the use of compact inductors and capacitors, saving PCB space while minimizing output ripple.

6. Comprehensive Protection Features

Over-Current Protection (OCP): Cycle-by-cycle current limiting for short-circuit prevention;

Over-Temperature Protection (OTP): Automatic shutdown upon exceeding temperature thresholds;

Over-Voltage Protection (OVP): Monitors input/output voltage anomalies;

Under-Voltage Lockout (UVLO): Prevents startup during insufficient input voltage to avoid abnormal operation.

7. AEC-Q100 Automotive Qualification

Certified to automotive reliability standards, supporting an operating temperature range of -40°C to +125°C, meeting stringent requirements for high temperature, vibration, and reliability in automotive electronics.

8. Thermally Enhanced TSSOP Package

Features a thermal-optimized TSSOP-EP (Exposed Pad) package, where the bottom thermal pad significantly improves heat dissipation, supporting high-power-density designs.

Applications

Automotive Electronics: Infotainment systems, dashboards, ADAS modules;

Industrial Power: PLCs, motor drives, communication equipment;

Battery-Powered Devices: Portable devices, IoT terminals.
