Product details
Overview
EVAL-L5963 from STMicroelectronics is an evaluation board for the L5963 dual DC-DC converter + LDO multichannel voltage regulator in PowerSSO-36 slug-down package. It supports independent 1.2 V/2 MHz and 5 V/250 kHz switching regulators (up to 3 A each) plus a 3.3 V/250 mA LDO, with onboard oscillator and input sync capability up to 2 MHz.
For engineers reviewing the EVAL-L5963 datasheet, EVAL-L5963 pinout, EVAL-L5963 application, or EVAL-L5963 equivalent, key selection factors include independent regulator enable control via jumpers, output voltage adjustability, dual-frequency operation support, and separate supply pins for DC-DC1, DC-DC2, and LDO.
Technical Context
The EVAL-L5963 implements full hardware validation of the L5963D regulator IC, enabling concurrent testing of both buck channels and the linear regulator under synchronized or asynchronous switching conditions. It provides direct access to FB, SYNC, EN, and PG signals for loop stability analysis and timing margin verification.
Board-level design includes dedicated test points for all critical nodes-input rails, switch nodes, feedback dividers, and LDO output-alongside jumper-configurable EN and SYNC routing to emulate real-system power sequencing and frequency coordination requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supported IC | L5963D in PowerSSO-36 package - enables full functional validation of this specific regulator variant |
| DC-DC1 Output | 1.2 V @ 2 MHz, 3 A - optimized for high-efficiency core rail generation in space-constrained applications |
| DC-DC2 Output | 5 V @ 250 kHz, 3 A - suited for higher-current peripheral or interface rail with lower EMI sensitivity |
| LDO Output | 3.3 V @ 250 mA - provides low-noise auxiliary supply for analog or communication circuitry |
| Frequency Control | Onboard oscillator + external SYNC input - allows precise frequency setting from 250 kHz to 2 MHz for EMI tuning or efficiency optimization |
| Configuration Flexibility | Jumper-selectable EN and output voltage adjustment - supports rapid prototyping of different power tree configurations without soldering |

FAQ
What is the difference between EVAL-L5963 and EVAL-L5963Q?
EVAL-L5963 supports the L5963D in PowerSSO-36 package, while EVAL-L5963Q supports the L5963Q in VQFPN-48. The boards share identical regulator functionality and layout topology but differ in footprint, thermal pad configuration, and PCB mounting compatibility due to their respective target packages.
Can EVAL-L5963 be used to evaluate L5963Q?
No. EVAL-L5963 is mechanically and electrically designed only for the L5963D in PowerSSO-36. The L5963Q uses VQFPN-48 with different pinout, pad layout, and thermal characteristics, requiring the dedicated EVAL-L5963Q board for accurate evaluation.
How is frequency synchronization implemented on EVAL-L5963?
The board accepts an external TTL/CMOS SYNC signal via J3 connector, allowing forced synchronization of DC-DC1 and DC-DC2 to an external clock source up to 2 MHz. An onboard oscillator (U3) also provides internal frequency generation when SYNC is disabled.
Are output voltages adjustable on EVAL-L5963?
Yes. DC-DC1 and DC-DC2 output voltages are set by resistor dividers (R1/R2 for DC-DC1; R17/R18 for DC-DC2), and the LDO output is fixed at 3.3 V. Jumpers JP1–JP4 allow independent enable/disable of each regulator, and test points TP1–TP6 provide direct access to all feedback and enable nodes.
