ABLIC launches its smallest Power Management IC (PMIC), the S-19560B, for automotive applications, supporting 16V input and three power output channels.
This series PMICs is ABLIC’s first to integrate two step-down DC-DC converter channels and one LDO regulator channel into an ultra-compact HSNT-8(2030) package (2.0 × 3.0 × t0.5mm).
In the circuit design of camera modules requiring downsizing, by combining the 3-channel output S-19560B Series with ABLIC’s small, high-PSRR LDO regulator (S-19255), designers can configure a four-channel power supply circuit with the industry’s smallest mounting area. This solution reduces the mounting area by approximately 20% compared with competing four-channel PMICs. Furthermore, utilizing an external LDO regulator offers the significant advantage of heat dispersion, contributing to space saving and improved thermal efficiencyof the camera module.
Additionally, image sensors and serializers often require different output voltages and power-up sequences depending on the manufacturer and device model. The S-19560B Series simplifies these settings by providing preset configurations, reducing both setup time and development effort.
In recent years, as vehicle technology accelerates—driven by CASE (Connected, Autonomous, Shared/Service, Electric)—the number of viewing and sensing cameras indispensable for Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD) has increased rapidly. The S-19560B Series was developed to address the various challenges that arise from this growing demand for automotive cameras.
The series provides small Package, with one of industry’s smallest mounting area, fitted into a proprietary package, HSNT-8(2030) (2.0 × 3.0 × t0.5mm). The minimum required external components are two coils and five capacitors. By adding one compact, high-PSRR ABLIC LDO (S-19255) and two capacitors, a power supply circuit with the industry’s smallest mounting area can be configured, achieving approximately 20% reduction compared with competing products.
The PMIC achieves heat dissipation via an external LDO. Also, by shortening the distance between the CMOS Image Sensor (CIS) and the LDO, external noise on the power line can be suppressed.
The product is shipped with the output voltage, startup sequence, and other parameters pre-configured. Therefore, it can be used immediately as a power supply after applying power, without the need for any initialization operations. This enables the power supply for the camera module to be constructed with a simple configuration.
