Texas Instruments TPS62A01AEVM-190

Overview

TPS62A01AEVM-190 from Texas Instruments is an evaluation module designed to validate the TPS62A01A 1-A synchronous buck converter in forced PWM mode. It accepts 2.5–5.5 V input and delivers a regulated 1.8 V output at up to 1 A, housed on a compact PCB with SOT563-packaged IC, test headers, and configurable jumpers for EN and PG monitoring.

For engineers reviewing the TPS62A01AEVM-190 datasheet, TPS62A01AEVM-190 pinout, TPS62A01AEVM-190 application, or TPS62A01AEVM-190 equivalent, this EVM supports rapid functional validation of low-voltage, high-efficiency DC-DC conversion in space-constrained embedded systems requiring stable 1.8-V rail generation and load transient assessment.

Technical Context

The TPS62A01AEVM-190 implements the TPS62A01A IC in a fixed-output configuration (1.8 V), leveraging its forced PWM operation to ensure consistent switching frequency across all load conditions - critical for EMI-sensitive applications. Input voltage sensing (J1 S+/S–) and output voltage sensing (J2 S+/S–) enable precise regulation verification without loading effects.

Hardware-level control is provided via JP1 (EN toggle) and JP3/JP4 (PG and GND access), while optional feedforward capacitor C4 (120 pF) and additional output capacitors (C5–C8) allow transient performance tuning. The board uses Murata GRM-series ceramics and DFE252012F-1R0M=P2 inductor for low-noise, high-reliability operation.

FAQ

What is the primary function of the TPS62A01AEVM-190?

The TPS62A01AEVM-190 is an evaluation module that demonstrates and validates the operation of the TPS62A01A 1-A synchronous buck converter. It provides a ready-to-use platform to verify 1.8-V output regulation, load transient response, efficiency, and forced PWM behavior across 2.5–5.5 V input. The TPS62A01AEVM-190 includes test points, jumpers, and layout-optimized components for immediate bench testing without custom PCB design.

How does the TPS62A01AEVM-190 differ from the TPS62A01EVM-190?

The TPS62A01AEVM-190 integrates the TPS62A01A IC, which operates exclusively in forced PWM mode across all load conditions, whereas the TPS62A01EVM-190 uses the TPS62A01 IC with automatic PFM/PWM transition. Both share identical board layout, connectors, and bill of materials except for U1 - making the TPS62A01AEVM-190 ideal for noise-sensitive or constant-frequency timing-critical applications where mode-hopping must be avoided.

Can the output voltage of the TPS62A01AEVM-190 be adjusted?

No - the TPS62A01AEVM-190 is configured for fixed 1.8-V output using resistor divider R1/R2/R3 per the TPS62A01A data sheet. Unlike adjustable versions, it lacks onboard trim components or solder jumpers for voltage reconfiguration. To evaluate other output voltages, users must refer to the TPS62A01A data sheet and implement external feedback networks - but the TPS62A01AEVM-190 itself is not field-adjustable.

What are the key test points and connectors on the TPS62A01AEVM-190?

The TPS62A01AEVM-190 features J1 (input: VIN/S+/GND), J2 (output: VOUT/S+/GND), and J3 (PG/GND) for direct probing of input/output voltage, sense signals, and power-good status. JP1 controls EN activation, JP3 exposes PG, and JP4 provides convenient ground access. These interfaces let engineers measure regulation accuracy, monitor startup sequencing, and correlate PG assertion with load transients - all without modifying the TPS62A01AEVM-190 hardware.

Is the TPS62A01AEVM-190 compatible with standard lab equipment?

Yes - the TPS62A01AEVM-190 is fully compatible with standard bench power supplies, electronic loads, oscilloscopes, and multimeters. Its 2.54-mm pitch headers (J1, J2, J3) accept common banana-to-clip or spring-loaded probes. Input and output sense lines (S+/S–) support Kelvin connections for accurate voltage measurement, and the GND-referenced layout minimizes ground loop errors during efficiency or ripple testing of the TPS62A01AEVM-190.
