Product details
Overview
STEVAL-ISA059V1 from STMicroelectronics is a DC-DC converter demonstration board based on the TSM108 step-down controller IC, designed for battery charging applications with 12 V input, 6 V regulated output, and up to 800 mA output current. It supports both P-channel MOSFET and PNP bipolar transistor power stages and includes multiple footprint options for flexible power semiconductor selection.
For engineers reviewing the STEVAL-ISA059V1 datasheet, STEVAL-ISA059V1 pinout, STEVAL-ISA059V1 application, or STEVAL-ISA059V1 equivalent, this board enables rapid evaluation of constant-voltage/constant-current (CV/CC) buck topologies in automotive accessory and portable power supply designs.
Technical Context
The board implements a synchronous or non-synchronous buck converter using the TSM108 - an integrated controller featuring internal reference (VREF = 2.5 V), error amplifier (ICOMP/VCOMP), oscillator (OSC), gate driver (GD), and undervoltage/overvoltage protection (UV/OV). Its ICTRL pin enables external current sensing for CC regulation.
Designed for cigarette-lighter-powered accessories, the board accommodates variable output power via interchangeable power stage footprints (Q1–Q4 positions), supporting discrete P-MOSFET or PNP configurations with external inductor (L1) and output capacitor (C14).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage | 12 V nominal - matches standard automotive battery and cigarette lighter socket supply. |
| Output Voltage | 6 V regulated - fixed CV setpoint suitable for sealed lead-acid or LiFePO₄ battery charging. |
| Max Output Current | 800 mA - defines maximum charge current capability under thermal and efficiency constraints. |
| Controller IC | TSM108 - integrates CV/CC control loop, reference, oscillator, and gate driver in one package. |
| Power Stage Support | P-channel MOSFET or PNP transistor - enables low-side sensing and high-side switching without bootstrap complexity. |
| Protection Features | UVLO and OVLO - prevents operation outside safe input voltage range (e.g., cold-crank or load-dump conditions). |
Availability

FAQ
Is STEVAL-ISA059V1 still in active production?
No - STEVAL-ISA059V1 is marked as obsolete per ST's official documentation (Rev 1, March 2009). It remains available through authorized distributors for legacy design support and educational use, but no new manufacturing runs are planned.
Can I replace the TSM108 on this board with a modern equivalent?
The TSM108 itself is obsolete and not recommended for new designs. ST does not list a direct drop-in replacement; engineers should consider newer buck controllers like the L6983 or VIPer0P series, though PCB layout and compensation networks would require redesign.
What power semiconductors are compatible with the Q1–Q4 footprints?
The board provides pads for both SOT-23 and SO-8 packages. Valid options include P-channel MOSFETs such as STS4DNF30L (SO-8) or DMG2305U (SOT-23), and PNP transistors like MMBT3906 (SOT-23), all verified in ST's schematic and bill-of-materials.
Does this board support adjustable output voltage?
No - the output is fixed at 6 V by resistor divider R6/R7 (10 kΩ / 10 kΩ) feeding the TSM108's VREF pin. Adjusting VOUT requires changing this divider ratio and verifying loop stability, as no onboard potentiometer or digital interface is provided.
