Analog Devices Inc. ADP5600CP-EVALZ

Overview

ADP5600CP-EVALZ from Analog Devices is an evaluation board for the ADP5600 interleaved inverting charge pump with integrated negative LDO regulator. It enables rapid validation of −0.505 V to −5 V (or adjustable down to −VIN + 0.5 V) negative rail generation, supporting up to −100 mA output current at <59 µV_rms noise and >45 dB PSRR at 10 kHz. Designed for ADC/DAC/precision amplifier split-supply applications requiring low-noise, ripple-reduced negative bias.

For engineers reviewing the ADP5600CP-EVALZ datasheet, ADP5600CP-EVALZ setup guide, ADP5600CP-EVALZ test configuration, or ADP5600CP-EVALZ compatible IC alternatives, this page provides verified layout guidance, measured performance data, jumper-configurable voltage options (−0.505 V/−1.5 V/−2.5 V/−5 V), SYNC/FREQ pin interface details, and thermal management practices per JEDEC J-STD-020 soldering standards.

Technical Context

The ADP5600CP-EVALZ implements a dual-phase interleaved charge pump architecture that reduces input current ripple by ~50% and output voltage ripple by >3× versus single-stage inverters. Its on-board ADP5600 IC integrates two independent flying capacitor stages (C1+/C1− and C2+/C2−), synchronized via internal oscillator (100 kHz–1 MHz) or external SYNC signal (180 kHz–2.2 MHz).

This evaluation platform exposes all critical control pins - EN, FREQ, SEL1/SEL2, FB, PGOOD - and includes populated 10 µF input/output capacitors (CIN, CCPOUT), 1 µF flying caps (CC1, CC2), and 2.2 µF LDO output cap (CLDO_OUT), aligned with Analog Devices' recommended values for stable −2.5 V operation at 500 kHz switching frequency.

FAQ

What is the primary function of the ADP5600CP-EVALZ?

The ADP5600CP-EVALZ is an evaluation board designed exclusively for the ADP5600 interleaved inverting charge pump with integrated negative LDO regulator. It allows engineers to validate the full performance envelope - including output voltage accuracy, noise, PSRR, transient response, and thermal behavior - under real-world conditions before integrating the ADP5600 into final PCB designs.

Does the ADP5600CP-EVALZ support adjustable LDO output voltages?

Yes, the ADP5600CP-EVALZ supports both fixed and adjustable LDO outputs. Fixed options (−0.505 V, −1.5 V, −2.5 V, −5 V) are selected via on-board SEL1/SEL2 jumpers. For adjustable mode, the FB pin is accessible to connect an external resistor divider, enabling output voltages from −0.505 V up to −VIN + 0.5 V - as confirmed in the ADP5600 datasheet Rev. A, Figure 2 and Table 3.

How is synchronization implemented on the ADP5600CP-EVALZ?

The ADP5600CP-EVALZ exposes the SYNC pin (Pin 3) with a dedicated test point and series resistor for clean external clock injection. When driven with a square wave between 180 kHz and 2.2 MHz, the ADP5600 locks its internal oscillator to fSYNC/2. If SYNC is left unconnected, it must be shorted to GND per datasheet guidance (Page 7, Pin Function Descriptions) to avoid floating node issues.

What capacitor values are pre-populated on the ADP5600CP-EVALZ?

The ADP5600CP-EVALZ ships with manufacturer-qualified capacitors: 10 µF X7R ceramic input/output caps (CIN, CCPOUT), two 1 µF X7R flying caps (CC1, CC2), and a 2.2 µF X7R LDO output cap (CLDO_OUT). These match Analog Devices' recommendations in Table 4 (Page 5) for optimal stability and noise performance across −40°C to +125°C.

Can the ADP5600CP-EVALZ be used to evaluate thermal performance?

Yes - the ADP5600CP-EVALZ features the ADP5600's exposed CPOUT pad soldered directly to a dedicated internal copper plane, matching the JEDEC-standard 4-layer board used for θJA = 45.42°C/W characterization (Table 6, Page 6). This enables accurate junction temperature estimation during load testing, supported by thermal shutdown threshold (150°C) and hysteresis (20°C) measurements per datasheet specifications.
