TPS657051 3 通道电源管理 IC
TPS657051 描述
TPS657051/52 are small power management units targeted for embedded camera module or other portable low power consumer end equipments. It contains two high efficient step down converters, a low dropout linear regulator and additional supporting functions. The 2.25MHz step-down converter enters a low power mode at light load for maximum efficiency across the widest possible range of load currents. For low noise applications the devices can be forced into fixed frequency PWM mode using the MODE pin. The device allows the use of small inductors and capacitors to achieve a small sized solution. TPS657051/52 provides an output current of up to 400mA on both DCDC converters and integrates one 200mA LDO with different output settings.
