STMicroelectronics STCMB1 | Demoboard STDES200GANADP
19 V - 200 W adapter reference design based on STCMB1, SRK2001A and MASTERGAN1
Overview
| Topology | Other Topology |
| IC revision | 1 |
Description
The STDES-200GANADP reference design is a 19V-200W converter tailored for the typical specification of an AC-DC adapter for all-in-one systems, gaming applications, SMPS for LED TV, and lighting applications. It ensures a wide input main range, a very low power consumption at light load, and a good average efficiency.
Features
- Common features
- SO20W package
- 800 V high voltage start-up with integrated input voltage sensing
- Active input filter capacitor discharge circuitry for reduced standby power compliant with IEC 62368-1 and UL Demko certified
- Independent debug mode for both converters
- PFC controller features
- Enhanced constant on-time PFC with input voltage feedforward, THD optimizer
- Complete set of protections: ac brownin/out, inrush control, OVP, OCP, inductor saturation, feedback disconnection
- LLC controller features
- Proprietary timeshift control for improved input ripple rejection and dynamic response
- Half-bridge operation up to 750 kHz with self-adjusting deadtime
- Complete set of protections: dc brown-out, two-level OCP, hard switching prevention (HSP) function for anti-capacitive mode protection and safe start-up
- Synchronous burst mode operation with PFC enhances light-load efficiency
Typical applications
- LED street lighting
- Ac-dc adapter, open frame SMPS, SMPS for LED TV, desktop and all-in-one PC
- Consumer andindustrial SMPS compliant with “Energy Using Product” directive (EuP) Lot 6, DOE and European CoC ver. 5, Tier 2
