Analog Devices Inc./Maxim Integrated ADPL13602EVKIT#

Overview

ADPL13602EVKIT# from Analog Devices is an evaluation kit designed to validate the ADPL13602 synchronous step-down DC-DC converter in a fixed 5V/2.4A output configuration, operating from a 6.5V–36V input supply at 500kHz switching frequency, with adjustable UVLO, soft-start, and open-drain RESET signaling.

For engineers reviewing the ADPL13602EVKIT# datasheet, ADPL13602EVKIT# pinout, ADPL13602EVKIT# application, or ADPL13602EVKIT# equivalent, this board provides a fully assembled, thermally optimized reference design for evaluating high-efficiency buck conversion under real load conditions with configurable EN/UVLO, MODE, and soft-start timing.

Technical Context

The ADPL13602EVKIT# implements the ADPL13602BATE+ IC in a TQFN16-EP (3mm × 3mm) package, configured for 5V output regulation with internal compensation. It uses a 15µH power inductor (Coilcraft XGL5050-153ME), 22µF output capacitance (TDK C3225X7R1C226M250AC), and supports both PWM and DCM operation via jumper JU2.

Input undervoltage lockout is resistor-programmable via R1/R2 (3.32MΩ/825kΩ default), setting turn-on at ~6.3V when JU1 is open. Soft-start time is set by C3 (6800pF default), yielding ~0.82ms startup, and RESET asserts low when VOUT drops below 92% of nominal (4.6V).

FAQ

What is the primary function of the ADPL13602EVKIT#?

The ADPL13602EVKIT# is a fully assembled evaluation kit that demonstrates the ADPL13602BATE+ synchronous step-down DC-DC converter in a 5V/2.4A configuration. It enables engineers to verify performance, validate thermal behavior, and assess system integration before final design. The ADPL13602EVKIT# includes all critical components, jumpers for mode and UVLO configuration, and a proven PCB layout optimized for efficiency and thermal management.

Does the ADPL13602EVKIT# support adjustable output voltage?

No, the ADPL13602EVKIT# is configured exclusively for a fixed 5V output using the ADPL13602's internal feedback network. The FB pin is tied to a precision resistor divider on-board, and no external voltage adjustment circuitry is provided. To evaluate other output voltages, users must refer to the ADPL13602 data sheet and modify the feedback network accordingly - the ADPL13602EVKIT# itself does not support reconfiguration beyond its 5V design point.

How is the soft-start time set on the ADPL13602EVKIT#?

The soft-start time on the ADPL13602EVKIT# is determined by capacitor C3 (6800pF), connected between the SS pin and SGND. Using the formula t_SS = C3 / (8.325 × 10⁻⁶), this yields ~0.82ms startup time. Users can adjust C3 to change soft-start duration - for example, increasing C3 to 10nF extends t_SS to ~1.2ms - enabling controlled inrush current limiting during power-up of sensitive downstream loads.

What protection features are implemented on the ADPL13602EVKIT#?

The ADPL13602EVKIT# inherits the ADPL13602's built-in overcurrent and overtemperature protections, which automatically disable switching and latch off under fault conditions. It also provides active-low open-drain RESET signaling (asserted low when VOUT falls below 4.6V), and optional input damping via C6 (47µF/50V electrolytic) to suppress voltage spikes during hot-plug events with long input cables - all verified per the ADPL13602EVKIT# Performance Report.

Can the ADPL13602EVKIT# operate in both PWM and DCM modes?

Yes, the ADPL13602EVKIT# supports both PWM and Discontinuous Conduction Mode (DCM) via jumper JU2. With shunt position 2–3 (default), the MODE pin is grounded and the ADPL13602 operates in PWM mode for best light-load efficiency. With shunt position 1–2, MODE connects to VCC and enables DCM mode, reducing switching losses at very low loads. This dual-mode capability allows direct comparison of efficiency curves across load ranges on the same board.
